Just recently, I've been having a problem when I turn on any of my equipment (BR player, HR24, Wii, Apple TV), I get no picture or sound on my TV. I have to turn the Onkyo receiver off and on again (sometimes more than once) to get picture or sound. My equipment is connected by HDMI to the receiver, which connects to the TV by HDMI. I suspect that the cable I'm using between the receiver and the TV has gone bad? Thoughts?
