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.

Is the power turned on again?
No
Check the back light lamp, D3600-3, Q3600-2 and their peripheral parts as well as pin (42) of IC2001.
Note: This model is equipped with the lamp error detection function that detects the current flowing into the fluorescent lamp and protects the backlight lamp drive circuit. If a lamp error is detected, the microprocessor interrupts the unit and the ERROR NO RESET setting will go up. When the ERROR NO RESET setting has reached "5", the microprocessor turns and keeps off the unit's power. To resume the power, take the above procedure to clear the ERROR NO RESET setting.
