Once you have a part number it might be easier to find it on the net.
Have you contacted Onkyo?
How old is your 508 and what can you afford to spend to get it going? It might be a better idea to just get a new one.
Ya I am more then comfortable taking the board out. I have seen them go for $70~ on ebay. An nope no noticible signs of anything on the hdmi board. I know I was rotating the receiver one time and heard a crunching sound at the hdmi jacks because my cables were to short. So I think that is truly what did the hdmi board in...
If I put less then $100 in, I would be happy to go back to it. I did pickup a onkyo 414 ($167) networking receiver for now, heck maybe for long haul. I like the massive amounts of hdmi, I like streaming from my ipad to the receiver, etc. I do wish it had audssey, and more power-clean power. But meh, it's all a trade off I guess.
If I can't source a known working hdmi board in the next two weeks, I thnk I am going to sell the 805s remote, power cord and anything else that people might want, hope to get $30-40 just for the remote.
