I have a TX-SR 806 that I purchased almost three years ago from Newegg. I'm having similar issues as some others that have posted, but not exactly.
My problem is that my receiver has recently started refusing to output any 1080p sources at seemingly random intervals.
It started happening a few weeks ago. At first I thought it was my htpc not outputting correctly, so I tested with a 360 and PS3 with the same results.
My cable box, Wii, and Apple TV work just fine since they are not 1080p sources.
All are hooked up via various decent HDMI cables, except for the Wii of course.
Any 1080p source just gives me no input messages on the receiver display and tv.
The HDMI out is set up to pass through to a brand new Samsung Plasma TV.
It will work perfectly for several days in a row and then just stop for no apparent reason. Power cycling and factory reset have no effect. If I just wait it out, it eventually starts working again, but seems to be getting progressively worse.
I haven't had any issues with blue dots, as I have the corrected "S" model. The on screen menu always works fine too since its a 480 signal.
Any ideas on what my problem may be here?
Would you be inclined to think its the HDMI board in my case as well?
Onkyo support just referred me to a service center half way across the country.
Any advice or info would be greatly appreciated.
