I'm using an Onkyo HT-R590 budget system between a Panasonic Bluray and TV. I'm also using it with a media center, an XBox, and a cable box.
Whenever I am using something for 10+ minutes I begin to have handshake issues. My screen flickers, loses signal, and sound goes out for increasing amounts of time. I originally thought this was an overheating issue but my receiver unit is getting plenty of ventilation. I called Onkyo for help and the guy just blabbed to me on and on about how HDCP works. He kept saying the problem must be with my TV.
So my question is this - is it my TV or my receiver and what can I do about it?
