Hi Jeff,
Talk about unluck of the draw! First, it seems that some of your components are getting quite hot?
Hey Jeff, what about CEC (Compatible Enable Components), you know that HDMI feature that operates your TV, receiver, and sometime a Blu-ray player, all together, by the simple push of a button? This feature is a bottleneck, real pain in the butt.
If I was you, I'll disable that feature from all your components.
It's very hard to pinpoint the issue, as you have quite alot of stuff in your system.
You might want to start all over again from the beginning; meanig plugging and connecting one component at a time. Try to keep things as simple as possible. And please, don't put anything on top of some of your components.
If you run out of space, just put them behind your components or somewhere that won't disturb the air flow, you know what I mean.
* The stangest thing is that it works before, and now suddenly, it won't!

That's why, I suggest to disable the CEC feature. Start with that, and we'll see what's next. But don't panick, and go running nude around the block, screaming at all your neighbours.

We'll found the problem, and come up with the solution, Ok?
Thanks for explaining the best you can, not many people do.
I'm sure other people will chime in, and come up with other suggestions, so don't despair.
*** By the way Jeff, Welcome to the Forum.
Cheers,
Bob
