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,

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.

  • Page 7: Self Diagnosis Function

    SELF DIAGNOSIS FUNCTION 1. PURPOSE AND OPERATION The DSP-A595a has a Self Diagnosis Function to locate a faulty part, if any, by inspecting and taking measurements. There are 11 main items in the diagnostic menu and some of them have sub-menu items as listed below.
  • Page 8 DSP-A595a 2. BEGINNING AND CANCELLATION (1) STARTING UP THE FUNCTION AND THE DISPLAY After starting up, menu No. 1 is selected. A. How to start diagnostic program Using the front panel keys of the main unit. Plug in the AC power cord , and, with Power OFF, hold down the "INPUT MODE" and "+" keys simultaneously (Step 1), and then press the "STANDBY/ON"...
  • Page 9 DSP-A595a 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.
  • Page 10 DSP-A595a 3. OPERATION AND DISPLAY WHEN STARTING DIAGNOSIS FUNCTION (1) Selection of diagnostic menu The diagnostic menu and the sub-menu can be selected by using the front panel keys of the main unit or the remote control unit. Selection by using the front panel keys The main menu can be changed cyclically by using the "TV SPORTS"...
  • Page 11 DSP-A595a 4. 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 DVD/LD MAIN BYPAS 1. MAIN BYPASS The MAIN L/R signals bypass the analog circuits to be output.
  • Page 12 DSP-A595a No.2 DSP THROUGH The input is automatically discriminated by signal detection and switched with priorities AC-3 (DOLBY DIGITAL)>DTS Digital Surround>Audio>analog. There are the following three submenus. 2 DVD/LD YSS918SRAM 1. YSS918-SRAM MAIN L/R are input to the DSP via AC3D2av, pass through SRAM, and are then output to all channels without being processed.
  • Page 13 DSP-A595a No.3 AC-3/DTS THROUGH The input is digital signal only. AC-3 (DOLBY DIGITAL) or DTS Digital Surround decoding operation is executed, according to the input source. bit 0 bit 7 3 DVD/LD 3T00000001 1. STATUS(BINARY FORM) AC-3 (DOLBY DIGITAL) decoded signals are output to each channel via AC3D2av.
  • Page 14 DSP-A595a No.5 SPEAKERS SET The input is automatically discriminated by AC-3(DOLBY DIGITAL)>DTS Digital Surround>PCM Audio>analog. There are the following 9 submenu items: The signal from the DSP block is normally in the effect off status for menu items 1-4. For other menu items, the same signal as in 2. DSP THROUGH: YSS918 menu is output.
