SERVICE MANUAL 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 of 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. 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. 1 0 0 6 7 8 AV AMPLIFIER DSP-A595a TO SERVICE PERSONNEL ........................................... 1 REMOTE CONTROL PANELS ....................................... 1 REAR PANELS ............................................................... 2 SPECIFICATIONS....................................................... 3~4 INTERNAL VIEW ............................................................ 5 DISASSEMBLY PROCEDURES .................................... 5 SELF DIAGNOSIS FUNCTION ................................ 6~17 FACTORY PRESET ...................................................... 18 I CONTENTS AMP ADJUSTMENT ..................................................... 19 IC DATA .................................................................. 20~30 DISPLAY DATA ........................................................... 31 BLOCK DIAGRAM .................................................. 32~33 PRINTED CIRCUIT BOARD ................................... 34~47 SCHEMATIC DIAGRAM ......................................... 48~53 PARTS LIST ............................................................ 54~67 REMOTE CONTROL TRANSMITTER ......................... 68 www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 1 DSP-A595a I TO SERVICE PERSONNEL 1. Critical Components information. Components having special characteristics are marked and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Model only). When service has been completed, it is imperative that you verify that all exposed conductive surfaces are properly insulated from supply circuits. • Meter impedance should be equivalent to 1500 ohm shunted by 0.15µF. • Leakage current must not exceed 0.5mA. • Be sure to test for leakage with the AC plug in both polarities. WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/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 handling food.

Appears when the protection function has not been activated. Appears when the current protection function has been activated. When power is turned on in an abnormal status, the power relay will come on, protection will operate immediately, and power will turn off. Appears when the power protection function has been activated. For the % value, the voltage at that point is shown by 5V/100%. When power is turned on in an abnormal status, power will turn off after half a second. Appears when the power amp DC protection function has been activated. For the % value, the voltage at that point is shown by 5V/100%. When power is turned on in an abnormal status, power will turn off after two seconds. G FL display at start-up of diagnostic program When the diagnostic program has started, the history (*2) of the protection function (*1) is displayed. If the protection function has been activated in the past, the type and voltage value are displayed. After a few seconds the diagnosis function menu will appear.

CONTENTS OF DIAGNOSIS FUNCTION This section describes the contents of the self diagnosis function in detail. No.1 ANALOG THROUGH The input is fixed to analog (A/D). There are two submenus. 1. MAIN BYPASS The MAIN L/R signals bypass the analog circuits to be output. For CENTER/LFE, FRONT L/R and REAR L/R, the MAIN L/R signals via the DSP are output without being processed (through).
