Quick service response. A useful and very rare service manual with all details. I recomend this service.
;
I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
;
The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual!
I'd definitely use owner-manuals.com again.
;
Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
 ;
Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.

6. Failures
A
� Depending on the types of errors, one of the following error messages will be displayed when the unit is turned on:
EEP ERR
1. Breakage or short-circuiting of the communication line to the EEPROM can be suspected. 2. A failure in the EEPROM can be suspected.
OC ERROR
B
� If "OC ERROR" is not displayed when the unit is turned on in Normal mode, short-circuiting of the speaker terminals can be suspected. � If "OC ERROR" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The line between one of the above digital amplifier ICs and the speaker terminals is short-circuited. 3. The XSD line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken.
OVERTEMP
C
� If "OVERTEMP" is not displayed when the unit is turned on in Normal mode, the unit is normal. (It is likely that this was a temporary temperature rise, lower the volume of the speakers.) � If "OVERTEMP" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The OTW line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken.
7. DSP error display
� Each time the SOUND key on the remote control unit is pressed while the power is on, the DSP error display and the normal display are alternately switched.
U TEST
8. Accumulated power-on time display and speaker setting display
� If the AUDIO INPUT key on the main unit is held pressed for 8 seconds while the power is on, the accumulated power-on time display and the speaker-setting display will be alternately switched at intervals of 3 seconds.

� Power-on time is always counted while the power is on, regardless of unit's functions and operations. However, it is not counted during Standby mode. � The maximum countable power-on time is 255H59M (255 hours 59 minutes.) The indication will not advance beyond that. � The accumulated power-on time basically cannot be cleared.
