Is anybody familiar with the electronics on this?
I switched it on one day, the LED flicked on and then off. I checked the output from the adapter and the voltage had gone high, so it looks like something blew. The question is, what?
Thanks for any ideas
I have not worked on a Mustek 600CU, but I was a electronics service tech for many years.
What Blew? If you are lucky, a fuse inside the scanner. If you are not lucky, some part in the power path inside the scanner blew.
In the power adapter, I would guess a voltage regulator blew (shorted on). Which means you need a replacement, if the scanner blew a fuse and not some part in the electronics.
You won't know until you open the scanner and look at the electronics.

No, nothing so easy as a fuse which is what I had been hoping for. I thought probably one of the diodes or a chip.
Anybody got a spare circuit board!
