Scanner HP 3500C Help

Guest · Posted: Mon Nov 12, 2007 7:04 pm Post subject: Scanner HP 3500C Help

I have a scanner HP 3500C that went into troubles. The scanned image looks green, noisy and blurred. Does anybody knows what cluld be the cause? I suspected the power supply since it crashed when using a chinese (generic) power adaptor. I replaced the 5V regulator - LM340T5, but no effect.

Can you give me a hint? If possible a service manual or schematics would be very helpful.
Help!
Thank you in advance
