Yamaha HTR 2064 Service Manual

HOME THEATER PACKAGE YHT-196RECEIVER / SPEAKERS HTR-2064 / NS-B20/NS-C20/NS-SWP20 SERVICE MANUAL The YHT-196 consists of the HTR-2064, NS-B20, NS-C20 and NS-SWP20. Note: • When the following parts are replaced, the destination MUST be written to the back-up IC (EEPROM: IC222 on DIGITAL P.C.B.) to have proper operation. (For details, refer to No. 22 SOFT SWITCH menu of the self-diagnostic function.) DIGITAL P.C.B. EEPROM: IC222 on DIGITAL P.C.B. • When the power amplifier IC (IC 1 or IC 2 on MAIN P.C.B.) requires to be replaced, be sure to refer to “POWER AMPLIFIER IC REPLACEMENT” before its replacement. IMPORTANT NOTICE This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel. It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understood by the users, and have therefore not been restated. WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA Retailer or the appointed service representative. IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form. The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division. NS-C20/NS-SWP20 HTR-2064/NS-B20/ WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit. ■ CONTENTS TO SERVICE PERSONNEL ............................................2 SELF-DIAGNOSTIC FUNCTION ...........................24–46 SYSTEM COMPOSITION ................................................3 DISPLAY DATA .......................................................47–48 FRONT PANELS .........................................................3–4 IC DATA ...................................................................49–60 REAR PANELS ...........................................................5–7 PIN CONNECTION DIAGRAMS .............................61–62 REMOTE CONTROL PANEL ..........................................8 BLOCK DIAGRAM ........................................................63 SPECIFICATIONS ..................................................... 8–14 PRINTED CIRCUIT BOARDS ................................. 64–76 INTERNAL VIEW .......................................................... 15 SCHEMATIC DIAGRAMS .......................................77–84 SERVICE PRECAUTIONS ............................................ 15 REPLACEMENT PARTS LIST ................................85–92 POWERAMPLIFIER IC REPLACEMENT ............... 16–17 REMOTE CONTROL ...............................................93–94 DISASSEMBLY PROCEDURES ............................. 18–20 ADVANCED SETUP ......................................................95 UPDATING FIRMWARE ..........................................21–23 Copyright © 2011 All rights reserved. 101227 This manual is copyrighted by YAMAHA and may not be copied or redistributed either in print or electronically without permission.

Critical Components Information WALL EQUIPMENT TESTER OR Components having special characteristics are marked and OUTLET UNDER TEST EQUIVALENT must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify INSULATING that all exposed conductive surfaces are properly insulated TABLE from supply circuits. • Meter impedance should be equivalent to 1500 ohms shunted • Leakage current must not exceed 0.5mA. by 0.15 μF. • Be sure to test for leakage with the AC plug in both polarities. For U model “CAUTION” “F1501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.” For C model CAUTION F1501: REPLACE WITH SAME TYPE 6A, 125V FUSE. ATTENTION F1501: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 6A, 125V. WARNING: CHEMICAL CONTENT NOTICE! This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before NS-C20/NS-SWP20 handling food. HTR-2064/NS-B20/ About lead free solder All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder. Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work. • Sn + Ag + Cu (tin + silver + copper) • Sn + Cu (tin + copper) • Sn + Zn + Bi (tin + zinc + bismuth) Caution: As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. 2 HTR-2064/NS-B20/NS-C20/NS-SWP20 ■ SYSTEM COMPOSITION The YHT-196 consists of the HTR-2064, NS-B20 x4, NS-C20 x1 and NS-SWP20 x1.
