Do not leave the module in high temperatures or in areas of high humidity for an extended period of time. Do not expose the LCD panel to direct sunlight. Avoid contact with water. It may cause a short circuit within the module. Disconnect the AC power when replacing the backlight or inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms.) 7. Always clean the LCD panel with a soft cloth material. 8. Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. 9. Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS). 10. During the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth. KDL-32BX311 3 SECTION 1 - SAFETY AND FEATURES SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer: 1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are “pinched” or touching high-wattage resistors. 3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators. 4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 7. Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. KDL-32BX311 4 SECTION 1 - SAFETY AND FEATURES LEAKAGE TEST To Exposed Metal Parts on Set The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA(500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instructions. 2. A battery-operated AC milliampmeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low voltage scale. The Simpson’s 250 and Sanwa SH-63TRD are examples of passive VOMs that are suitable. Nearly all battery-operated digital multimeters that have a 2 VAC range are suitable (see Figure A). AC Voltmeter (0.75V) 0.15 µF Earth Ground Figure A. Using an AC voltmeter to check AC leakage. HOW TO FIND A GOOD EARTH GROUND The cover-plate retaining screw on most AC outlet boxes is at earth ground.Verify the AC outlet box retaining screw ground by connecting a 60-to 100-watt troublelight (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure B). Trouble Light AC Outlet Box Figure B.

KDL-32BX311 9 SECTION 2 - SOFTWARE REQUIREMENTS OVERVIEW There are 2 reasons for updating the software on the TVs. ‡ Software updates for customers These updates are for enhancements or improvements that have been made to the software after the TV was released. ‡ Software update for servicers 7KHVH XSGDWHV DUH VSHFL¿FDOO\ IRU VHUYLFHUV WR XVH GXULQJ D service call. SOFTWARE UPDATES FOR CUSTOMERS The subject of software updates is a very important. The televisions of today have advanced to the point where they are not simply a television anymore. They are evolving into devices that are designed to integrate with numerous other devices found in the home. Some examples are: Portable audio and video devices, still cameras, home computer networks and accessing the internet to name a few. Communications with these varying devices requires that the television be compatible with varying communications protocols. Although standards are detailed for each of these protocols, the real world dictates that occasional errors may occur that could prevent devices from operating or communicating properly. Keeping the software in the television up-to-date is a procedure that is normally handled by the owner of the television. Most customers who own computers and other digital devices are familiar with and are accustomed to updating the software in their products. If a customer contacts the Sony Customer Support Center and it is deemed to be correctable with a software update, the issue is handled at the customer level. KDL-32BX311 10 SECTION 2 - SOFTWARE REQUIREMENTS SOFTWARE UPDATES FOR SERVICERS The models in this manual utilize a “generic” type main board.

Service adjustment information is covered in “Section 7 - Service Adjustments” on page 36. SOFTWARE UPDATE RESPONSIBILITY Software updates are designed to be performed by the customer. Warranty repairs in which the issue can be resolved by a software update are not reimbursable. Most issues involving software updates are handled by the customer service center and should not be directed to an authorized service center. It is the responsibility of the servicer to prevent service calls for issues that involve software updates. Exceptions to this are certain cases whereby the customer is unable or unwilling to perform the task. In this situation, WKH VHUYLFHU ZLOO EH QRWL¿HG DQG UHFHLYH WKH SURSHU DXWKRUL]DWLRQ IRU reimbursement. It is the servicer’s responsibility, however, to make certain that any TV requiring a legitimate service is running the latest software version and to install it if necessary. CHECKING THE SOFTWARE VERSION The easiest way to check the version of software that is currently on the TV is to access the Contact Sony screen by using the customer menu. FIGURE 2-1.

NOTE: For connector part number information, refer to “Connectors” on page 34. For Wire Dressing information, refer to “Wire Dressing” on page 35. A G13 SWITCH UNIT H FIGURE 3-1. CIRCUIT BOARD LOCATION KDL-32BX311 13 SECTION 3 - CHASSIS OVERVIEW OVERALL CIRCUIT DESCRIPTION “Figure 3-2. Block Diagram” on page 16 provides an overview of the AZ2-UK chassis. Below is a description of the components and their functions. MAIN BOARD (A BOARD) Common to all models utilizing the AZ2-UK chassis, the Main Board (A Board) contains most of the video processing circuitry along with all audio processing. Control of the television is accomplished via a CPU embedded within the MT5388 processor. Below is a list of the key components located on the Main Board. TUNER The tuner is a combination ATSC/NTSC unit. It can receive traditional analog NTSC signals via cable or terrestrial along with ATSC digital signals via terrestrial (8VSB) or cable (64 or 256 QAM). Audio Processing: Analog audio sources are selected and A/D converted directly by U3. The audio information is then processed digitally. Digital audio from the tuner and HDMI sources is also input DQG SURFHVVHG &ODVV ' DPSOL¿HU 8 SURYLGHV WKH GULYH IRU WKH speakers. HDMI Input and Switching: The customer can select the HDMI1 or HDMI2 input. Each HDMI input contains a dedicated EDI NVM (not shown) to provide display information data to any device connected via the HDMI inputs. CPU: The CPU internal to the MT5388 processor controls all aspects of the television functions. Input from the user along with monitoring of critical circuits is also performed by this CPU. LVDS Transmitter: Integrated into U3 is a Low Voltage Differential Signaling (LVDS) transmitter. This circuit converts the 8-bit parallel RGB video information into a set of high speed serial lines for noisefree transmission to the TCON circuits located internally to the LCD panel. MT5388 PROCESSOR IC U3 performs the majority of the necessary audio and video processing on the A board. Analog Video Input Switch: All analog video sources are selected and A/D converted and scaled (if necessary) to 1280 X 720p 60HZ resolution. Digital Audio and Video Decoder: The MPEG2 and Digital Dolby audio streams are received from the tuner for decompression. All video sources which are not native 1280 X 720p 60HZ are scaled to this resolution. Digital audio content is RXWSXW WR WKH FODVV ' DPSOL¿HU IRU SURFHVVLQJ DQG DPSOL¿FDWLRQ KDL-32BX311 14 SECTION 3 - CHASSIS OVERVIEW POWER SUPPLY BOARD (G13 BOARD) LCD PANEL ASSEMBLY The Power Supply Board for this model is designated as the G13 Board. The LCD Panel Assembly includes the LCD Panel, TCON Board, and LED Backlight system. There are 2 distinct sections on the power supply: 7KH /&' 3DQHO FRQWDLQV WKH DFWXDO OLTXLG FU\VWDOV FRORU ¿OWHUV DQG polarizers. The liquid crystals are manipulated by the applied voltage WR SDVV D VSHFL¿F DPRXQW RI OLJKW IURP WKH EDFNOLJKW GHSHQGLQJ RQ the level of voltage applied. Standby Supply: Continuously operational as long as AC power is applied, the standby supply generates 3.3VDC for the circuits requiring power while the unit is turned off. An unregulated 15-volt line is present to provide power to the main relay, PFC and main power supply at turn-on. Main Supply: Once the power supply receives a power-on command from the CPU on the A board, the main switching supply is turned on to provide a regulated 12V source, a dedicated un-regulated 15V for the audio circuits and an unregulated 24V source for the inverter circuit. The TCON performs all the control, timing, charge, and discharge functions driving the operation of the LCD Panel. A new LCD Panel assembly from parts will include the following items. LCD Panel TCON Board LED Backlight System SWITCH UNIT This board contains the power, channel, and volume up/down and menu buttons. IR BOARD Designated as the H Board, the IR Board contains the power, standby, and timer LED’s are located on this board along with the IR remote receiver and light level sensor. INVERTER The inverter receives the unregulated 24V from the power supply board and generates the required high voltage AC to power the backlight lamps. A control line to turn on the inverter (backlights on) is used in conjunction with a dimmer control to vary the light level of the CCFL lamps. As of the writing of this manual, the inverter is not available as a replacement part. The LCD panel assembly must be replaced. TCON BOARD The TCON Board communicates between the LCD Panel and the microprocessor on the Main Board. (NOTE: The TCON Board is not available as a replacement part for all models.)

BLOCK DIAGRAM KDL-32BX311 16 SECTION 4 - TROUBLESHOOTING OVERVIEW Most troubleshooting for this chassis focuses on the 3 major components used: x The Main Board (A) x Power Supply Board (G13) x LCD Panel This chapter provides practical troubleshooting procedures based on the various symptoms that will appear when a particular circuit fails to operate properly. Typical failure symptoms will be discussed LQ WKLV FKDSDWHU ZLWK WURXEOHVKRRWLQJ ÀRZFKDUWV IRU HDFK V\PSWRP LQ the “Section 5 - Flow Charts and Diagrams” on page 26. UPDATING THE SOFTWARE As mentioned in “Section 2 - Software Requirements” on page 10, there are several issues that may be resloved by updating the software to the latest version. For a list of possible correctable issues see “Checking the Software Version” on page 11. VIDEO FAILURES Problems that develop in the video circuits can appear as subtle or major distortions, a loss of one or more colors, improper video level, or a complete loss of video. When troubleshooting LCD display devices the problem must be isolated to 2 major components: The main board where the video processing is performed or the LCD panel. In some cases the TCON may not be available as a separate component and replacement of the LCD panel is required to rectify a TCON problem. Distortion in the video signal that affects all inputs can be challenging at times since any of the above mentioned components can be the cause. Fortunately, each of these components tends to generate unique symptoms when a problem occurs. Some distortions may occur that could be caused by either of these components but a good understanding of the circuits and further investigation will isolate the suspected circuit. The following sections will cover the various scenarios of problems that may occur in the video processing circuits. NO VIDEO A “no video” complaint can be caused by a number of reasons. The ¿UVW VWHS LV WR GHWHUPLQH LI WKH FRQGLWLRQ LV SUHVHQW IURP DOO LQSXW sources. If any video source is working properly, the TCON (located within the LCD panel) can be assumed to be OK. The backlights are also functioning properly. Although it is unusual for a backlight failure to cause a complete loss of video (the TV will shut down if a backlight power or open LED is detected) there have been cases where the backlights have failed to turn on without the unit shutting down. KDL-32BX311 17 SECTION 4 - TROUBLESHOOTING If the loss of video occurs on all inputs, the problem will require additional diagnostic work. The presence of audio is an important sign to check for. Missing audio accompanying a loss of video helps to eliminate the TCON as the cause and would point to the main board as the culprit. If audio is present, the next step is to determine if the video loss is occurring in the video process circuits on the main board, or the LVDS cable link from the main board to the LCD panel. VIDEO DISTORTION 7KLV LV SHUKDSV WKH PRUH GLI¿FXOW IDLOXUH WR GLDJQRVH ,W LV GLI¿FXOW when talking to the customer on the phone because an accurate description of the problem must be obtained in order to determine ZKLFK SDUW RU SDUWV WR EULQJ WR WKH ORFDWLRQ ,W PD\ DOVR EH GLI¿FXOW for the technician when the problem is witnessed. Service Tip: If a service call is made for a “no video” complaint, a warranty repair would require the technician to bring the main board to the location. Install the main board and if the video problem is not resloved it is safe to assume the problem might reside in the TCON.

LCD Panel: Distortions originating from the LCD panel tend to be localized with the exception of horizontal line issues. A failure of a gate driver can cause a horizontal distortion with all video content below that point appearing distorted. Depending on which gate driver has failed, the distortion may only cover a small area of the bottom of the screen if the driver failed near the bottom of the panel, or a large area of the screen if the driver failed near the top of the panel. With the exception of visible physical damage, the following are some examples of LCD panel related distortions: KDL-32BX311 A thorough understanding of how the video is processed throughout the chain of circuits all the way to the panel is important. A past article written for the Sony Newsletter described, in detail, how this process works. “Figure 5-2.

Under normal circumstances, any failures in the backlighting system will cause the unit to shut down. If any section of the inverter circuits fails to operate properly, the unit will shut down and blink the standby LED in groups of 6. x Failure of the main supply including the main switching regulator, PFC circuit, main relay and other components required to turn the circuits on. ,I RQH RU PRUH RI WKH ÀXRUHVFHQW EDFNOLJKWV IDLOV WR OLJKW WKH RYHU voltage protection circuit of the inverter is activated. The inverter shuts down and the same 6-blink protect event occurs. x The power supply is not receiving a turn-on command from the CPU. The recommended approach for a 6-blink shutdown is to determine if the backlights are turning on before the shutdown. The easiest way to determine this is to watch for the Sony logo to appear on the screen. The television will make 2 or 3 attempts to achieve proper lighting of the lamps. If the Sony logo appears, the backlights are turning on and the problem is likely due to one of the lamps not lighting. If the lamps never turn on and no Sony logo appears on the screen, the inverter is the likely suspect. COMPLETELY DEAD SET A complete power supply failure is generally the result of severe transients in the AC line such as those incurred during an electrical storm. This model line utilizes a red standby LED located on the lower left front bezel that is lit whenever the TV is receiving AC power and is turned off. If it is not lit, and AC power to the television LV FRQ¿UPHG UHSODFHPHQW RI WKH SRZHU VXSSO\ ERDUG VKRXOG UHFWLI\ the problem. TV WON’T POWER ON This situation assumes that the red standby LED is lit when AC power is applied to the TV. A lit standby LED indicates that the standby power supply is operational, and the CPU on the main board is at least partly operational. In this case it is likely that the main power supply is either not being turned on or it has failed. Use the power-on button on the right side of the TV to attempt a turn-on and eliminate a defective remote control system. “Figure 5-3. Power Supply Flowchart” on page 28 will assist in isolating the power problem. KDL-32BX311 NO BACKLIGHT, NO SHUTDOWN It is possible for a symptom of no backlighting to occur that does not cause the television to go into protective shutdown. Dynamic dimming control of the backlights is performed by monitoring information from the TCON circuits. This is in the form of data and determines the brightness level of the backlights based on video content. If the TCON fails to process the RGB video data, or if the dimmer data line fails, the backlights will not turn on. Audio will be present if the selected input has it available. The television will remain on LQGH¿QLWHO\ ZLWK WKH JUHHQ 3RZHU /(' OLW ,Q WKLV VFHQDULR WKH /&' panel must be replaced. 20 SECTION 4 - TROUBLESHOOTING PROTECTION SHUTDOWN STANDBY LED FLASH COUNT Self Diagnosis Supported model Critical voltages and circuit operations are monitored by the CPU on the main board.

The following list contains the protect circuits and diagnostics codes used in the models listed in this manual. “Figure 5-4.

BLINK COUNT KDL-32BX311 21 SECTION 4 - TROUBLESHOOTING 2X Blink - Main Power Error 6X Blink - Backlight System Failure A loss of REG12V from the power supply triggers this protect event. This symptom is usually remedied by replacing the power supply board. If the error continues after the power supply board is replaced, suspect excessive loading which is causing the power supply to shut down. This is usually caused by a failure of the inverter circuits. Unplug the inverter and turn the TV back on. If a 6X error is displayed, the inverter (or LCD panel) must be replaced. If the inverter circuits fails to generate high voltage or one or more of the backlight lamps fails to light, the television will shut down and display this diagnostics error. Observing for the presence of backlighting is crucial in determining which component is likely at fault. 3X Blink- DC Regulator/Audio Error The REG 5V and D3.3V source originating on the main board is monitored for low-voltage conditions by the CPU. A failure causing a 3X shutdown would require replacing the main board. 5X Blink - TCON Error A communications error with the timing control circuits (TCON) has occurred. If the TCON is available for replacement, replace the TCON. If the TCON is not available, the LCD panel must be replaced since the TCON circuit is part of the LCD panel assembly. In rare cases a loose or defective LVDS cable could also be the cause. KDL-32BX311 If the backlights turn on before the 6X shutdown occurs, it is safe to assume that the inverter circuits are functioning and one of the lamps failed to ignite. Replacing the LCD panel is necessary. If the backlights never turn on before the 6X shutdown, the inverter has failed. If the inverter is available for replacement, replace the inverter. If the inverter is not available, replace the LCD Panel. 7X Blink - Temperature Failure A digital thermometer IC located on the main board provides a temperature reading of the chassis and LCD panel. If the temperature exceeds a pre-determined point the TV will shut down. If this problem occurs immediately at turn-on, the temperature sensing IC has failed and replacing the main board is required. If this occurs after the TV has been running for a while, check for ventilation issues that could cause the TV to run hotter than normal. 22 SECTION 4 - TROUBLESHOOTING DIAGNOSTIC CODE DESCRIPTIONS The Diagnotic Table provides an overview of the number of times the Standby LED blinks and the possible location.
