Onkyo HT-R680 green and bouncing picture

[hizzaah]

When I turned on the tv/stb/receiver this morning, the picture had a ton of lines and everything was tinted bright green while jerking up and down. After ~30sec the green and lines would go away, but the picture was still moving. Audio was fine though.

I switched over to my BR and it was fine so I decided to plug in a new hdmi from my stb to my tv so I could make sure it wasn't either of those. They were fine, I moved the new cable back to the receiver. Picture was fine. Just for giggles I put the old one back into the stb and receiver, no audio but picture was fine. Switched input to my BR, the back to the STB and the audio was now perfectly fine.

So not sure if it was just the hdmi coming loose, or if this is a sign of things to come for my receiver. Anyone have experience with their onkyo hdmi ports going out? Anything like this happen?

I have the receiver well cooled with a fan, so heat isn't a factor..

The HDMI boards failing on Onkyo receivers, is a common and well documented problem. If you search this and AVS forum you will find a lot of threads on this.

The problem is too much heat build up frying the caps. The solution if you are handy is to recap the HDMI board with caps of a higher temperature rating and add fans. If a service center replaces the board it is expensive and the problem recurs. The heat build up is apparently due to poor board layout, and the fans have to be placed internally.

If the problem goes uncorrected it can fry the processor on that board which is a bigger problem.
