content: I checked out the capacitors and they are okay.I do have 5V and 12V. The unit does not completely turn on. I do get a display over hdmi but the display on the unit does not light up.I have asked Pioneer to send me a service manual but they won't. I can not find a service manual or schematic anywhere. I saw a post on HIFI-Forum.DE from a rich neuling and tried to contact him but no answer.I know this is an old thread but maybe someone came across a service manual since the last post.

content: I had eye surgery and put this repair on hold. I just got around to put it back on my bench.I will check out the dimmer function to see if the display is turned off.

content: I'd like a slim-line receiver like this for my bedroom as the speakers in modern TVs suck. It would definitely need to be able to be dimmed completely if I were to sleep with music playing.Sadly, these units are a bit expensive. I'd like to see some internal pictures of this unit.
