Welp... I crossed my fingers and was hoping you were on to something. So just to be thorough, I re-tried all the HDMI cables, directly to the TV.
Core i3 directly into to the TV. In 1080p. No problems.
Using the same cables... Panny 3D BD directly into to the TV. In 1080p. Ice Age FULL 3D. No problems.
(BTW, 3D works -perfect- with HDMI 1.3 cables AFAICT with audio and video--can't speak for audio return channel or ethernet.)
Then I put the 576 in the mix. 576 insists that there's "No Signal". Screen is black... no sound. Not even static.
So I don't think the cables are a problem. And having ruled out a problem with any of my other hardware... And with all the people reporting various manifestations of HDMI problems with 576s and 606s, it's got to be the receiver.
As far as the cold start theory, I can tell you that my receiver is on all day long. And it's in a fairly enclosed media cabinet, so it's pretty much hot all the time. Definitely fully warmed up by the time I get to troubleshoot it. If anything... overly hot.
Of note... as I speak, my wife is watching Gossip Girl 1080i off my PVR and it's starting to show some bizzare artifacts--albeit intermittent and rarely. Strange greenish lines I've not seen before. Mind you, the PVR is 1080i... never 1080p.
I'll bet that I've pushed the 576 to death with the heat, that this is the beginning of the death knell. My 1080i is starting to go maybe?
I don't think there's a definitive way to tell unless I take it to the shop. But there's no way I'm going to pay to diagnose/repair this rig professionally. I think I only paid about $200 for it in the first place.
I think I'm going to take the dive and just pick up an RC260. Some decent upgrades. And there's some great deals on pre-owned units on Amazon.
If anyone wants to experiment with an orphaned 576 that doesn't seem to switch/pass 1080p... swing by Hoboken, NJ and I'll let you have it after I get my new receiver.
