This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
 ;
Impeccable, document très complet. Perfect, i get all i need. All schematic are correct. Thanks
;
The manual is of better quality compared to other. I found it less expensive and therefore it it is the best buy cost vs quality.

I bought the service-manual of the sony ICB-1020(an old transmitter-receiver) at "www.Owners-Manual.com", I found the service-manual for a fairly cheap price(in comparison with other sellers). I filled in some questions, payed the order with Ideal, and within 24 hours I had my service manual. I was very happy:In no time I had my service-manual and everything, but literally everything was noted down in the manual; the electronic scheme, the parts list, etcetera.
A very practical, reference-document.

This comprehesive service maual was greatly appreciated, as was the digital download.
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.
