Onkyo TX-SR808


Standard Member
I've been experiencing a persistent problem of audio/video dropout since I upgraded from a TX-SR805 to the TX-SR808.
I have a Samsung LCD connected to my Main HDMI out and a Sony Projector to my Sub HDMI.
Everything is fine except that when I'm running my projector I get a total drop out of audio and video after exactly 2 hours repeated by another about a minute later, then all is well again.
This has been going on ever since I got the receiver and I have tried all sorts of options..new HDMI leads, firmware upgrades, Changed HDMI monitor out settings, etc.
The only solution which appears to work is to manually select HDMI sub only when I want to use the projector and then HDMI main only when I wish to switch back to TV. Then everything works perfectly.
I am unable to use the Both, Both/Main or Both/Sub settings in the HDMI monitor-out setup selector.
Anyone have any ideas?
