They are categorized as either Rear Projection or Di- rect View. Rear Projection Television Technologies: • CRT • LCD • DLP™ • LCoS Direct View Television Technologies: • Plasma • LCD This training manual is directed towards Projection Tele- vision technologies. Each technology offers its own strengths and weaknesses. Otherwise, only one type would need to be made available. Understanding the differences in each technology will aid the technician when discussing a given set’s performance with a consumer. Tables 1-1 and 1- 2 outline some of the strengths and weaknesses of each one. Of course, the strengths and weaknesses will change as each technology evolves over time. CRT Technology - V27 Chassis This is the most mature technology of the four. It may even be viewed as somewhat “low tech” by some people. However, Mitsubishi’s product line includes all the latest digital features. As such, it can still offer the best “bang for the buck” of all the technologies. The V27 Chassis is used in 55”, 65” and 73” models. LCD Technology - V28 Chassis While LCD projection television is certainly not new, recent strides have improved this technology so that Mit- subishi can offer it in 4 models this year. DLP Technology - V29/V30/V31 Chassis Mitsubishi, the first to bring DLP technology to market in a rear projection television, marks another “first” by introducing 1080p DLP in 9 different rear projection models. This is twice the resolution of High Definition. It will come in 52, 62 and 73 inch screen sizes, with the 73 inch models being the largest DLP models ever available. LCoS Mitsubishi’s use of LCoS technology is in the form of a 3 chip system carried over in the 82” rear projection model WL-82913.

Since the V25 Train- ing Manual covers it in-depth, no further discussion will be necessary. LCD, DLP and LCoS are known as “Micro-Display” technologies. The Light Engines are configured differently for each. LCD uses the “light transmissive” method of producing a picture as light passes through the panel. DLP and LCoS use the “light reflective” method of producing a Figure 1-1: LCD Light Engine picture as light reflects off the surface of the display device. An LCD must use 3 devices to produce a color picture. DLP and LCoS can be configured as either single, or 3 device engines. Mitsubishi currently uses a single chip DLP and a 3 chip LCoS system. The LCD Light Engine, shown in Figure 1-1, uses 3 LCD “Panels” to individually produce the red, green and blue elements of the picture. Dichroic mirrors separate the red, green and blue elements of light, and an X- Prism is used to re-combine the 3 colors after the pictures have been produced. Projection Lens Mirror Red Blue X Prism Dichroic Mirror Green Dichroic Mirror Lens Lens Lens Mirror Mirror Lamp LCD LCD LCD 1-3 Figure 1-2: DLP Light Engine Projection Lens Shaping Lens Lamp Condensing Lens Relay Lens DMD TIR Prism Color Wheel The single device DLP Light Engine, shown in Figure 1-2, produces a color picture using a color wheel and the “field sequential” method of displaying the red, green and blue elements of the picture. Figure 1-3 shows an LCoS engine in a 3 chip arrangement. Like LCD, it produces each color individually. And like DLP, it uses reflective light to produce the picture.

LCD Improvements: • Quick Motion™ • SmartShutter™ DLP Improvements: • 1080p • Dark Detailer™ • 10,800 RPM Color Wheel Quick Motion™ is an advanced high speed drive system that derives faster response from LCDs, virtually eliminating the blurs that often occur when the moving picture has fast motion. SmartShutter™ is a dynamic aperture system that improves black levels and adds a large palette of dark grey shades. It does this by reducing light output during dark scenes without negatively affecting other picture characteristics. Shown in Figure 1-4, the SmartShutter High Contrast Unit (HCU) is located in the light path between the lamp output and the optics. The HCU is a motor driven device that dims the lamp output by physically blocking it with movable louvers. See Figure 1-5. As dark scenes are detected, the louvers move from position A, full light output, through positions B, C and D to accurately control the amount of light necessary as the picture brightness varies. It is controlled by the PWB-Motor Driver. Figure 1-4: Smart Shutter Location in LCD Light Engine SmartShutter High Contrast Unit (HCU) SmartShutter Control PWB Fan LCD Drive PWB Projection Lens Lamp 1-5 Motor Louvers Motor Louvers A B C D Lighting Area A B C D Lighting Area Figure 1-5: Smart Shutter High Contrast Unit The 1080p technology in Mitsubishi’s DLP product line offers twice the pixel resolution of 720p HDTV. See Figure 1-6. Not only does this technology give a full 1920 x 1080 resolution, it does so using half the micromirrors. This yields a smooth appearance without “pixel gaps.” A comparison of a 720p DMD and a 1080p DMD is given in Figure 1-7. A 720p DMD uses a square pixel arrangement while a 1080p DMD uses a diagonal pixel arrangement. Pixel gaps are eliminated by dividing the 1080p picture into 2 sub-frames and interleaving the image by shifting the second subframe down by 1/2 pixel. See Figure 1-8. The image shift is accomplished with the use of a single coil driven mirror located in the optical output stage of the DLP light engine. See Fig- ure 1-9. Figure 1-6: 1080p vs. 720p 1-6 Figure 1-7: 720p DMD vs. 1080p DMD Pixel Arrangement Square Pixel Arrangement Diagonal Pixel Arrangement Final Pixel Image 1280X720 1920X1080 720p DMD Chip 1080p DMD Chip 720p DMD 1080p DMD 1-7 Figure 1-8: Sub-frame Integration The data is divided into two subframes, each with half the original data. During one of the subframes, the image is shifted down by 1/2 pixel. The eye integrates the two consecutive subframes to create the final image. This process is completd every 1/60 of a second, displaying all of the data, every frame, just as is the case for other traditional DMDs. The resulting image exhibits the same pixel resolution as the original input data in both horizontal and vertical directions, using half the number of mirrors. The gaps are also minimized in the process, resulting in an image that is not only full resolution, but smooth in appearance - without the typical pixel gaps. 1-8 Figure 1-9: DLP Light Engine - 1080p and Dark Detailer Modules Dark Detailer™ is another type of dynamic aperture system used with DLP based models. It displays deeper blacks and better dark scene detail. The location of the Dark Detailer, also referred to as the Dynamic Black (DB) module, is shown with its cover removed in Figure 1-9. It is located in the light path between the lamp and DLP optics. Figure 1-10 shows the DB module after it has been removed from the engine. The light shutter can be seen at the top of the picture. It moves into and out of the light path to reduce the lamp output during dark scenes. An aperture opening in the shutter can also be seen. Figure 1-11 depicts how the one-sided aperture system provides the best reliability along with better contrast and uniformity over the entire TV picture. 1080p Module Dark Detailer Dynamic Black (DB) Module Figure 1-10: Dark Detailer Module 1-9 Figure 1-11: One Sided Dynamic Aperture Because some people can experience a “rainbow effect” due to differences in their persistence of vision, a 10,800 RPM Color Wheel is now used in the 2005- 2006 DLP product line. This represents a 50% speed increase over last years 7,200 RPM wheel. Service Technologies The 2005-2006 PTV product line carries several technologies that affect service. They are: • PWBs are constructed with Lead Free Solder. • Mirror area is easier to access on 52” LCD & all DLP to simplify cleaning. • Elimination of ribbon cables in the Electrical Chassis improves reliability. • The Interface PWB between the Chassis and Light Engine is convenient for troubleshooting. • Access to the Electrical Chassis is improved for troubleshooting and PWB replacement. • LED diagnostics have been expanded to simplify troubleshooting. These topics will be discussed further in this manual. 2005-2006 PTV Product Line Specifications for the 2005-2006 PTV product line are given starting on the following page. 1-10 ÌEEE1394 ÌNPUT/OUTPUT DÌGÌTAL AUDÌO ANT-1 MAÌN ANT-2 AUX (DTV/CABLE/VHF/UHF) MONÌTOR OUTPUT AUDÌOVÌDEO1 CableCARD¯USEWÌTH ANT1 CARDTOP V|deo Features P|us|¹ lrad|rd · Coro F||ler Vol|or-Adapl|ve 180-L|re 30 Y/C Auloral|c F||r Vode |3:2 pu||doWr corpersal|or) · 0el|rEdde¹ \3V 3e|eclao|e ov |rpul l0T\ 3carr|rd Rale 1080| P|clure Forral Vodes lor ara|od 180|/180p ard 1:3 d|d|la| sources ê P|clure Forral Vodes lor ara|od 1080| ard d|d|la| 1ê:9 sources 2 P|cture Performance Co|orTured¹ 3||e|d user-Rerovao|e CRT 3|ze Z¨ w3-5551Z ard w3-ê551Z 9¨ w3-Z351Z User |nterface Control Feetures NelCorrard Ü · Cao|eCorrard¹ |0|d|la| Cao|e Corlro|) · C|arre|\|eW¹ |0r-screer C|arre| L|sl) · lR 3vsler Corlro| W|l| Learr|rd Vode · PerleclCo|or¹ / Aulo Co|or Correcl|or 3e|eclao|e ov |rpul Fu|| 3creer Freeze Frare · P/P/P0P Feetures Vu|l|-lrade 1 PlP, 3 ard 9 P0P 3p||l 3creer · C|arre| Prev|eW/lrpul 3lrooe |ara|od c|arre|s or|v) · Aud|o 3pea|ers w3-5551Z, w3-ê551Z, w3-Z351Z 5¨ Fu|| Rarde x 2 0ulpul PoWer |walls) 10w x 2 Tun|ng 0|d|la| Turer |A|r/Cao|e-AT3C/0AV) 1 Ara|od Turer |A|r/Cao|e) 2 Cao|eCAR0¹ 3|ol Yes Antenne lRF} /nputs Ara|od / 0|d|la| Coro|red 2 Cao|eCAR0¹ 3|ol · A\ lrpuls |Ara|od) A/\ lrpuls W|l| 3-\|deo |Frorl/Rear) W|l| 3lereo Aud|o 1/2 Corporerl \|deo lrpuls W|l| 3lereo Aud|o 2 |180|/180p/1080|) AV 0utputs [Ana|og} Vor|lor A/\ 0ulpul |lor record|rd) · 3lereo Aud|o 0ulpul |l|xed aud|o) · |nputs|0utputs [0|g|ta|} F|rew|re Ü |lEEE 1391) |Frorl/Rear) 1/2 l0Vl¹ W|l| ara|od slereo |rpul 1 0|d|la| Aud|o 8|lslrear 0ulpul |0o|ov Ü 0|d|la|) 1 |coax|a|) |nc|uded Accessor|es Vu|l|orard l||ur|raled Rerole Corlro| l||ur|raled lR Er|ller Cao|e 1 |2-|eaded) 0|d|la| Coax|a| Aud|o Cao|e d 1 Fealures, spec|l|cal|ors ard d|rers|ors are pre||r|rarv ard are suojecl lo c|arde.

(View from Front of unit) 2-8 2-9 Lead Free Solder Mitsubishi's 2005-2006 product line, including the V28, V29, V30 and V31 chassis, will be constructed using lead free solder. This is the first part of a 3 phase program to eliminate the lead content in all MDEA's electronic products. The 3 phases are: • Phase 1… PCB's constructed using Pb-free solder. PCB surface finishing and components may contain Pb. • Phase 2… Solder, PCB surface finishing and component lead plating is Pb-free. Components may have internal Pb. • Phase 3… Solder, PCB surface finishing and components are Pb-free. (100% Pb-free) Pb-Free Phase Definition Display Short Display (When the area is too small) Phase-1 PCB's constructed using Pb-free solder. Phase-2 Solder, PCB surface finishing and component lead plating is Pb-free. Components may have internal Pb. Phase-3 Solder, PCB surface finishing and components are Pb-free. (100% Pb-free) Table 2-1: Pb-Free Phases and Symbols Pb PCA Pb Joints Pb S Pb J Pb P Pb Solder Displays used to indicate Pb-free PCBs will be marked, indicating the level of Pb-free construction. Table 2-1 defines the levels by phase and shows the different symbols that will be displayed on the PCB. Additionally, a PCB constructed using Pb- free solder may be simply marked LFS. When possible, the indication will be placed close to the part number that is screened onto the PCB (not the part label). Figure 2-1 is an example of a PCB showing the display and its location. Pb free solder differs from conventional leaded solder. • The amount of tin in Pb-free solder is greater. • The melting point of Pb-free solder is higher. Figure 2-1: Pb-Free Display on PCB Pb-Free Display 2-10 Also, Lead-free solder does not "wet" as well as leaded solder. That means it has trouble adhering to both the soldering iron tip and the surface being soldered. To counteract this, the flux used is more corrosive. Lead- free solder also does not change from solid to liquid or back again all at once. It passes through a soft state. So, the melting process actually occurs through a range of temperatures. This makes a significant impact when repairing PCBs using Pb-free solder. Problems that can be encountered working with Pb-free solder are: • Excessive heat can cause the PCB to warp, detaching surface mount components. • Excessive heat may cause thermal damage to components. • Excessive heat can cause plastics such as connectors, relays, LEDs, electrolytic capacitors, etc. to melt or warp. • Higher temperatures can cause surface oxidation resulting in poor solder spread-ability and wet-ability. • The flux is more corrosive. • The time required for a good solder connection may be longer. • Poor wet-ability can cause solder balls. • Higher temperatures can cause flux spattering. • Soldering iron tip life is shortened. • Duller finish solder joint can appear to be a "cold" solder joint. Pb-free Hand Soldering Hand soldering with lead-free solder doesn’t necessarily require higher soldering temperatures. The melting time will be slightly slower than with leaded solder, requiring an increase in contact time. The solder joint will also look different. It will have a dull finish that is similar in appearance to a "cold" solder connection when using leaded solder. To help eliminate problems working with lead free solder, consider the following points. Temperature… Use the same soldering temperature as you would with tin-lead solder, about 700 F. If hotter, you may be making it more difficult to solder. The higher temperature causes oxidation to form faster, making wetting even more difficult. Excessive temperatures can also lengthen the cooling time, allowing micro-cracks to form within the joint. Thermal Recovery…Use a soldering iron with good thermal recovery. When the iron is first applied to a cool joint, the heat transfer causes the tip temperature to drop. A higher powered iron will bring the tip back up to the proper temperature faster. Using a shorter tip will also improve thermal recovery. Thermal Conduction… Use the widest tip possible in relation to the joint being soldered. This will allow the heat to conduct to the joint better. Also keep the tip wetted for better heat transfer. Tip Cleanliness… Important! Keep the soldering iron tip clean at all times using a damp sponge. Re-tin the tip before returning the iron to its stand. To extend the tip life, do not leave the iron on when it is not being used for longer periods of time. De-soldering… For the same reasons as soldering, increasing the temperature for de-soldering is not desirable. However, if a vacuum de-soldering tool is used, the solder must remain molten from the tip, all the way to the entrance to the filter. If the solder hardens along the way, it can clog the tool. Solder When performing repairs, it is necessary to use solder as that is compatable with that used in the original manufacture. Leaded solder cannot be used when soldering PCBs manufactured with Pb-free solder. And, Pb-free solder cannot be used on PCBs manufactured using leaded solder. The Mitsubishi standard for service requires the use of Tin-Silver-Copper ( Sn-96.5, Ag-3.0, Cu-0.5) solder. It can be obtained through the Parts Department.

The 2005-2006 Micro-Display product line lends itself to this discipline very well. Using The Front Panel LEDs The front panel LEDs, Figure 4-1, provide an indication of the sets operation, and the possible cause of a malfunction. There are three front panel LEDs, “Power”, “Status” and “Lamp”. Which LED is lit, the color and whether it is blinking or steady indicates to the customer the current status, or a possible malfunction. Using the Front Panel LEDs is similar for LCD and DLP based sets. The indications are also listed in the Owners Guide. Figure 4-1: Front Panel LEDs Normal Indications… The LEDs provide the customer with status information that indicates several normal operational modes. Normal indications are give in Table 4-1. Abnormal Indications… The LEDs also provide the customer with status information indicating abnormal conditions. Abnormal indications are give in Table 4-2.

Or, when the TV turns On and then shuts Off, the Self Diagnostics help isolate the problem. This is similar to the Self Diagnostic feature on previous model TVs. For both the V28 and V29/30/31 Chassis, it has been greatly expanded. The Self Diagnostics activation procedure is described as follows: 1) With the TV Off 2) Press and hold the front panel "MENU" and "DEVICE" buttons for 5 seconds. 3) The LED will flash the Error Code indicating what caused the TV to shut Off. 4) The Error Code will be repeated 5 times. When the LED stops flashing, the mode is automatically terminated. Error Code Description 12 No error detected 32 Lamp Cover open 33 Air Filter Cover open 34 Lamp abnormality 35 DM Fan failure 36 Exhaust or Lamp Ballast Fan failure 37 LCD Engine Fan failure 38 Lamp temperature abnormally high 39 LCD temperature abnormally high 41 Short is detected 42 Lamp Fan failure 44 DVI cable between Format and Engine disconnected 45 Shutter (PBS) Fan Failed 46 JC connector disconnected 47 DM Temperature too high 48 Engine power supply short detected 51 Speaker short detected 56 Shutter not connected Error Code Description 12 No error detected 32 Lamp Cover open 34 Lamp abnormality 35 DM Fan failed (Chassis Fan) 36 Exhaust or Lamp Ballast Fan failure 37 DMD Engine Fan failure 38 Lamp temperature abnormally high 39 DMD temperature abnormally high 41 Short is detected (Standby Power Supplies) 42 Lamp Fan failure 44 DVI cable between Format and Engine disconnected 46 DMD Fan failed (JC connector disconnected) 47 DM Temperature too high 48 Engine power supply short detected 51 Speaker short detected 52 HDD excess temperature (V30+ & V31 only) 55 HDD Fan Stopped (V30+ & V31 onlyt) Table 4-3: Error Codes V28 ERROR CODES V29/V30/V31 ERROR CODES Reading the Error Codes The Error Codes are two digit numbers. The LED: • Flashes the value of the most significant digit (MSD). • Then there is a pause. • Flashes the value of the least significant digit (LSD). • The Error Code is repeated 5 times. Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times then repeat the sequence 5 times. If the technician is still uncertain of the code, repeat the procedure. After the error code is known, troubleshoot the area indicated. For instance, if excessive temperature is indicated when the set is known to be cool, suspect a failed sensor. 4-3 Interface Troubleshooting The Interface PWB provides the service technician with a convenient test point for many of the peripheral components such as the Engine, Lamp Circuit, Fans and Sensors. It is easily accessible as it is located in the center of the set, directly in the rear of both the LCD and DLP models. Figure 4-2 shows the layout of the Interface for the LCD, V28 Chassis. Figure 4-3 shows the layout for the DLP, V29/30/31 chassis. These layouts are as the technician is viewing the PWB from the rear of the set. To save time, use the Symptom/Cause information along with the Circuit Block Diagrams to make checks on the Interface PWB first. Figure 4-2: V28 Chassis PWB Interface Layout… As viewed from the rear. Figure 4-3: V29/30/31 Chassis PWB Interface Layout… As viewed from the rear.

The material in this chapter covers differences in circuitry between the LCD and DLP chassis. Since troubleshooting will be mainly to board level, the Power Supplies, Signal Path and Control circuitry connections and paths between the various PWBs is also described. The simplified Block Diagrams should help in isolating problems to a specific PWB. Power Supply Basic Description Figure 5-1 shows the Basic Power Supply that is the basis for all the chassis types. The Main Power Supply is on PWB-POWER. The main Standby, Switched and Ballast DC supplies are generated on the PWB- POWER. It is also the source for the Fan Power Sup- plies located on the PWB-INTERFACE. On the DLP chassis, a PWB-ENG-PWR board is added. This board generates the DC supplies required by the DLP Engine. In the V30+ and V31 chassis models, a Hard Disc Drive (HDD) has been added. The additional Power Supply Figure 5-1: Basic Power Supply Block Diagram 5-2 for the HDD is located on the PWB-POWER for these two chassis types. Due to differences between the various chassis there are three version of the PWB-POWER. These are listed in Table 5-1. Switch Mode Regulator The Switch Mode Regulator (SMR) on the PWB- POWER is the initial source for all DC Supplies except the DC supply for the Ballast. Figure 5-2 shows a simplified diagram of the Switch Mode Regulator. This circuitry is conventional and is Figure 5-2: Switch Mod Regulator PWB Part Number Models ASSY-PWB-POWER1 930B933001 All V28 models ASSY-PWB-POWER2 934C159001 WD-52627 / WD-52628 / WD-62627 / WD-62628 / WD-73727 ASSY-PWB-POWER2 934C159002 WD-62727 / WD-62927 / WD-73827 / WD-73927 Table 5-1: PWB-POWER Part Numbers 5-3 the same on all three of the PWB-POWER boards. It is the original source for both Standby and Switched supplies. With the TV Off, AC from the PS connector is applied to D9A00 through R9A01. The SMR generates +15V, -15V and 18V standby supplies. The +15V and -15V supplies are the source for switched +15V and -15V supplies. The 18V supply is the source for all other standby supplies. Regulation is achieved by monitoring the 18V supply, and comparing it to a reference in IC9A20, Any error in voltage is coupled through PC9A10 to the SMR IC9A10. When the TV is switched ON the MAIN RELAY command goes High, closing K9A10 which removes current limiting resistor R9A01 from the circuit.

DC to DC Converters. A comparison of DC supplies generated on the LCD and DLP Power Supply boards is shown in Tables 5-2 and 5-3. Note that there is no Switched 12V or 5VR supplies generated on the LCD Power board, and no switched 18V supply is generated on the DLP Power board. The DC to DC Converter circuitry on the LCD Power board is illustrated in Figure 5-3A. The DC to DC Converter circuitry on the DLP Power board is shown in Figure 5-3B. The difference in circuitry in Figure 5- 3 is high lighted by shading. 5-4 Figure 5-3A: V28 PWB-POWER DC to DC Supplies 5-5 Figure 5-3B: DLP PWB-POWER DC to DC Supplies 5-6 Ballast DC Supply This circuit is the same on all three Power boards. A simplified version of the circuit is shown in Figure 5-4. Fan DC Supplies and Control The DC supplies for the fans are generated on the PWB-INTERFACE board,. The circuitry is supplied by the 18VF Standby Supply on the PWB-POWER. The actual Fan Supply circuitry on the PWB-IN- TERFACE differs between LCD and DLP models. Figure 5-5 illustrates the circuitry in LCD models and Figure 5-6 the circuitry in DLP models. Differences in the circuitry are high lighted in Fig- ure 5-6. Note that Fan control signals are from the PWB-FMT, through the FC connector on LCD models, and through the FB connector in DLP models. Figure 5-4: Ballast DC Supply Figure 5-5: V28 Fan Power Supplies 5-7 PWB-ENG-PWR It was previously mentioned that the PWB-ENG-PWR board is added in DLP models. Figure 5-7 shows this circuitry. It is basically a PWM Regulator with a push pull FET output circuit, generating a 2.5V supply for the DLP Engine. The board also serves as an interface for the 12V, 5V and 3.3V Standby supplies from PWB- POWER. Hard Disc 7Drive (HDD) Supply Additional power supply circuitry is required for the V30+ and V31 chassis. Both of these chassis types feature a Hard Disc Drive. Added power circuitry for the HDD is on the PWB-POWER, refer to Figure 5-8. Note that the Fan Stop monitoring circuit for the HDD is also added to PWB POWER. Power Distribution When a specific PWB is suspected as the cause of a problem, the following should be checked before ordering a new board: • Power supply voltages supplied to the PWB. • Signals supplied to the PWB. Power Distribution diagrams are helpful in locating the source of a missing power supply voltage. Figure 5-9 shows the Power Distribution for the V28 chassis. Fig- ure 5-10 illustrates Power Distribution in the DLP chassis. Although the two chassis types are similar there are some differences. The shaded areas in Figure 5-10 indicate differences from the V28 chassis. Figure 5-6: V29/V30/V30+/V31 Fan Supplies 5-8 Figure 5-7: DLP Engine Power Supply Figure 5-8: Hard Disc (HDD) Power Supply (V30+ and V31 Only) 5-9 Figure 5-9 5-10 Figure 5-10 5-11 Video Signal Path Analog Video Path The Video signal path is also similar on all the chassis types. Figure 5-11 illustrates the Basic Analog Video Signal Path. The Tuners are located on the PWB-DM. The Analog video from the Tuners is directed through PWB-RISER to the Video Select Circuitry on PWB- MICRO. The Video Select circuitry is comprised of IC2K01 and IC2KO2. IC2K01 selects the Sub Video signal source and the External Video Input source for the Main Pic- ture. It then forwards the External Main Picture signal to IC2K02. IC2K02 selects the main picture source from the signals from IC2K01, an External Component input or the Main Tuner.. The selected Main and Sub Video signals are directed through the PWB-RISER to A/D Converters on PWB- DM. The outputs from the A/D Converters are directed to 3DYC, Line Double and PIP/POP circuitry. The signals from the PWB-DM are directed to the PWB-FORMAT. The signals are digital Y,Pb,Pr. In the V28 chassis the signals are in 720p format. In the DLP chassis the signals are in the 1080i format. On the PWB-FORMAT the signals are processed and converted to the drive format for that specific Engine. In the DLP PWB-FORMAT, the signals are converted from 1080i to 1080p. Figure 5-11:Basic Analog Signal Path 5-12 Digital Video Signal Path Figure 5-12 illustrates the Basic Digital Video Signal Path. The Digital Signal output from the Main Tuner is an I.F. signal. The signal from the Main Tuner is directed to PWB-DEMOD1. The Demodulated Output (MPEG) signals are direct back to PWB-DM and via the POD circuitry to the MPEG Decoder. The output of the MPEG Decoder is processed by Doubler and PIP/POP circuitry and is directed to the PWB-FORMAT. Note that Prelude and A/D Converter circuitry added in the DLP chassis PWB-FORMAT. These used for signal conversion to 1080p and to process signals from a PC. In V29 through V30+ chassis PC connection is though one of the HDMI inputs on the rear of the TV. In the V31 chassis a conventional VGA input is added on the PWB-FORMAT. Note the in the V30+ and V31 chassis the PWB- DEMOD2 is added to process HD signals from the Sub Tuner. This allows the Sub Tuner HD signals to be selected as the PIP/POP sub picture signal source. As a reference for troubleshooting, Figures 5-13 through 5-15 are more detailed Video Signal Path diagrams: Figure 5-13: Analog Video Signal Path Figure 5-14: Digital Video Signal Path Figure 5-15: Record Signal Path Shaded Areas differ from the V28 circuity.

The Sound Circuitry is the same on both LCD and DLP chassis. IC3J01 on PWB-TER- MINAL select the analog sound signal source. The selected signal is directed to PWB-DM. The signal is converted to a digital I2S format and is applied the Digital Sound Selection portion of the HD Processor. The signal is then directed to an MP3 Switch. If the signal source is digital, it is processed by an MP3 Decoder and is also directed to an input on the MP3 Switch. An I2S Decoder converts the selected signal to analog left and right audio. The signals are directed through PWB-RISER and are processed by a sound processing IC, then amplified and directed to the set’s speakers. The only new circuitry is Speaker Short Detect circuit shown in Figure 5-17.

Differences from the V28 chassis are shaded in Figure 5-20. Mainly in the V28 the LAMP-EN command is from the FMT µPC, and in the DLP chassis it comes from the Light Engine Figure 5-20: DLP Chassis Lamp Control Circuitry 5-18 Engine Protect Circuitry This circuitry monitors the temperature in the Light En- gine, and Lamp, and also monitors the operation of the various cooling fans. Figure 5-21 shows the Engine Protect circuitry in the V28 chassis, and Figure 5-22 the Engine Protect circuitry in the DLP chassis. The main difference between the two circuits is there is no Air Filter in the DLP chassis, so there is no FILTER DET status line. The FILTER-DET line is shaded in Figure 5-21. Short & Speaker Protect Circuitry As a quick reference, the Short Protect circuitry is illustrated in Figure 5-23 There are two Short Protect circuits, one for Standby Supplies and one for Switched Supplies (PON supplies)..

LCD Technology . LCD. LCD uses the “light transmissive” method of producing a picture as light passes through the panel. or 3 device engines. The LCD Light Engine. no further discussion will be necessary. Mitsubishi currently uses a single chip DLP and a 3 chip LCoS system. uses 3 LCD “Panels” to individually produce the red. X Prism Projection Lens Mirror LCD LCD Red Lens Green LCD Mirror Blue Dichroic Mirror Lens Lamp Dichroic Mirror Lens Mirror Figure 1-1: LCD Light Engine 1-2 . and an XPrism is used to re-combine the 3 colors after the pictures have been produced. Dichroic mirrors separate the red. DLP and LCoS can be configured as either single. green and blue elements of light. The Light Engines are configured differently for each. shown in Figure 1-1.Light Engines The CRT technology used in the V27 chassis is electrically the same as the V25 chassis. DLP and LCoS use the “light reflective” method of producing a picture as light reflects off the surface of the display device. DLP and LCoS are known as “Micro-Display” technologies. green and blue elements of the picture. An LCD must use 3 devices to produce a color picture. Since the V25 Training Manual covers it in-depth. produces a color picture using a color wheel and the “field sequential” method of displaying the red. shown in Figure 1-2. Like LCD. Figure 1-3 shows an LCoS engine in a 3 chip arrangement. it uses reflective light to produce the picture.

The image shift is accomplished with the use of a single coil driven mirror located in the optical output stage of the DLP light engine. Not only does this technology give a full 1920 x 1080 resolution. it does so using half the micromirrors.” A comparison of a 720p DMD and a 1080p DMD is given in Figure 1-7. Figure 1-6: 1080p vs. This yields a smooth appearance without “pixel gaps. A 720p DMD uses a square pixel arrangement while a 1080p DMD uses a diagonal pixel arrangement. Pixel gaps are eliminated by dividing the 1080p picture into 2 sub-frames and interleaving the image by shifting the second subframe down by 1/2 pixel. See Figure 1-6. See Figure 1-8.Motor A B Louvers D C Lighting Area Figure 1-5: Smart Shutter High Contrast Unit The 1080p technology in Mitsubishi’s DLP product line offers twice the pixel resolution of 720p HDTV.

So. all the way to the entrance to the filter.5) solder.Also. It will have a dull finish that is similar in appearance to a "cold" solder connection when using leaded solder. • Soldering iron tip life is shortened. Thermal Conduction… Use the widest tip possible in relation to the joint being soldered. A higher powered iron will bring the tip back up to the proper temperature faster. Pb-free Hand Soldering Hand soldering with lead-free solder doesn’t necessarily require higher soldering temperatures. Cu-0.0. That means it has trouble adhering to both the soldering iron tip and the surface being soldered.

The Mitsubishi standard for service requires the use of Tin-Silver-Copper ( Sn-96. Thermal Recovery… Use a soldering iron with good thermal recovery. • Poor wet-ability can cause solder balls. it can clog the tool. De-soldering… For the same reasons as soldering. To help eliminate problems working with lead free solder. Problems that can be encountered working with Pb-free solder are: • Excessive heat can cause the PCB to warp. However. LEDs. do not leave the iron on when it is not being used for longer periods of time. Tip Cleanliness… Important! Keep the soldering iron tip clean at all times using a damp sponge. Pb-free solder cannot be used on PCBs manufactured using leaded solder. the heat transfer causes the tip temperature to drop. consider the following points. Leadfree solder also does not change from solid to liquid or back again all at once. allowing micro-cracks to form within the joint. Order part number: PB FREE SOLDER 2-10 . The melting time will be slightly slower than with leaded solder. if a vacuum de-soldering tool is used. It can be obtained through the Parts Department. Leaded solder cannot be used when soldering PCBs manufactured with Pb-free solder. • Higher temperatures can cause flux spattering. Lead-free solder does not "wet" as well as leaded solder. you may be making it more difficult to solder. Using a shorter tip will also improve thermal recovery. Also keep the tip wetted for better heat transfer. This will allow the heat to conduct to the joint better. This makes a significant impact when repairing PCBs using Pb-free solder. relays. To counteract this. to melt or warp. • Higher temperatures can cause surface oxidation resulting in poor solder spread-ability and wet-ability. the solder must remain molten from the tip. • Excessive heat can cause plastics such as connectors. increasing the temperature for de-soldering is not desirable. etc. Temperature… Use the same soldering temperature as you would with tin-lead solder. detaching surface mount components. The solder joint will also look different. To extend the tip life. the flux used is more corrosive.

Since troubleshooting will be mainly to board level. a Hard Disc Drive (HDD) has been added. V30. The Main Power Supply is on PWB-POWER. a large part of the circuitry is the same or very similar in all chassis types. Switched and Ballast DC supplies are generated on the PWBPOWER. On the DLP chassis. Switch Mode Regulator The Switch Mode Regulator (SMR) on the PWBPOWER is the initial source for all DC Supplies except the DC supply for the Ballast. Figure 5-2 shows a simplified diagram of the Switch Mode Regulator. These are listed in Table 5-1. Due to differences between the various chassis there are three version of the PWB-POWER.PWB ASSY-PWB-POWER1 ASSY-PWB-POWER2 ASSY-PWB-POWER2 Part Number 930B933001 934C159001 934C159002 Models All V28 models WD-52627 / WD-52628 / WD-62627 / WD-62628 / WD-73727 WD-62727 / WD-62927 / WD-73827 / WD-73927 Table 5-1: PWB-POWER Part Numbers for the HDD is located on the PWB-POWER for these two chassis types. This circuitry is conventional and is Figure 5-2: Switch Mod Regulator 5-2 . When the TV is switched ON the MAIN RELAY command goes High. AC from the PS connector is applied to D9A00 through R9A01. Although the SMR circuitry is the same on all PWBPOWER boards. The +15V and -15V supplies are the source for switched +15V and -15V supplies. -15V and 18V standby supplies. With the TV Off. DC to DC Converters. and comparing it to a reference in IC9A20. the Standby and Switched DC to DC Converter circuitry does vary according to chassis type. The DC to DC Converter circuitry on the LCD Power board is illustrated in Figure 5-3A. and no switched 18V supply is generated on the DLP Power board. A comparison of DC supplies generated on the LCD and DLP Power Supply boards is shown in Tables 5-2 and 5-3. Regulation is achieved by monitoring the 18V supply. Any error in voltage is coupled through PC9A10 to the SMR IC9A10.3V ENG-PWR-ON 5VSL 12V ENG-PWR-ON +15VSA 5VR PWR-ON -15VSA +15VS PWR-ON -15VS PWR-ON 340V LMP-RLY Table 5-3 5-3 .

The selected Main and Sub Video signals are directed through the PWB-RISER to A/D Converters on PWBDM. In the DLP PWB-FORMAT. It then forwards the External Main Picture signal to IC2K02. The Tuners are located on the PWB-DM. In the V28 chassis the signals are in 720p format. The signals from the PWB-DM are directed to the PWB-FORMAT. IC2K01 selects the Sub Video signal source and the External Video Input source for the Main Picture. the signals are converted from 1080i to 1080p. Figure 5-11 illustrates the Basic Analog Video Signal Path. The signals are digital Y. The outputs from the A/D Converters are directed to 3DYC. IC2K02 selects the main picture source from the signals from IC2K01.Pb. On the PWB-FORMAT the signals are processed and converted to the drive format for that specific Engine. The Analog video from the Tuners is directed through PWB-RISER to the Video Select Circuitry on PWBMICRO. an External Component input or the Main Tuner. Figure 5-11:Basic Analog Signal Path 5-11 . In the DLP chassis the signals are in the 1080i format. The Video Select circuitry is comprised of IC2K01 and IC2KO2.Pr. The output of the MPEG Decoder is processed by Doubler and PIP/POP circuitry and is directed to the PWB-FORMAT. Note that Prelude and A/D Converter circuitry added in the DLP chassis PWB-FORMAT. In V29 through V30+ chassis PC connection is though one of the HDMI inputs on the rear of the TV. Note the in the V30+ and V31 chassis the PWBDEMOD2 is added to process HD signals from the Sub Tuner.F.
