Quick site processing. A complete and very useful manual with all details. Thank you!
;
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.
TROUBLESHOOTING
FLOW CHART NO.1 The power cannot be turned on. Is the fuse normal? Yes Is normal state restored when once unplugged power cord is plugged again after several seconds? No No See FLOW CHART No.2 <The fuse blows out.> Check if there is any leak or shor-circuiting on the primary circuit component. (Q1001, Q1003, T1001, D1001, D1002, D1004, D1005, D1011, C1003, C1005) Check each rectifying circuit of the secondary circuit and service it if defective. No No No No Check POWER button (SW2001) and their periphery, and service it if defective. Check EV+5V line and service it if defective. Replace DVD Main CBA unit. Check Q2007 and their periphery, and service it if defective.
Yes Is each voltage of the secondary side normal? Yes When pressing POWER button (SW2001), is the voltage of 0V supplied to pin(8) of IC2002? Yes Is the voltage of 5V supplied to pin(1) of IC2002? Yes Is the voltage of 3.3V outputted to pin(19) of CN1001? Yes Is the voltage of 0V supplied to pin(18) of IC2002? Yes Replace IC2002. FLOW CHART NO.2 The fuse blows out. Check the presence that the primary component is leaking or shorted and service it if defective.
Check the presence that the rectifying diode or circuit is shorted in each rectifying circuit of secondary side, and service it if defective.
After servicing, replace the fuse. FLOW CHART NO.3 When the output voltage fluctuates. Does the photo coupler circuit on the secondary side operate normally? Yes Check IC1001, D1012, D1024 and their periphery, and service it if defective. No Check IC1001, IC1006, D1015, D1048 and their periphery, and service it if defective.
FLOW CHART NO.4 When buzz sound can be heard in the vicinity of power circuit. Check if there is any short-circuit on the rectifying diode and the circuit in each rectifying circuit of the secondary side, and service it if defective. (D1003, D1006, D1008, D1016, D1030, IC1002, Q1002, Q1004, Q1010, Q1011, Q1014, Q1050) FLOW CHART NO.5 -FL is not outputted. Is -24V voltage supplied to the anode of D1003? Yes Check if there is any leak or short-circuit on the loaded circuit, and service it if defective. No Check D1003 and periphery circuit, and service it if defective.
