Advertisements OK, here's my situation. We've been running our Tivo box in HDMI directly to a Panasonic plasma (commercial model with DVI "blade" installed), without problems, for about 10 weeks now. A couple of days ago, I'm getting the dreaded thermal shutdown. If I reboot and don't plug in the HDMI cable, all is well. As soon as the HDMI cable is plugged in, within 5 minutes I get the shutdown message. I am running the "f" version of the software, which is supposed to correct this problem. I tried disconnecting my DVI switch box, and connecting the DVI cable directly to the Tivo box, with the same results. I went to Best Buy and picked up a new Tivo box, and still get the same results. (Will be returning that new box.) (edit: I should add that this is obviously caused by the HDMI, and not actual thermal overheating -- the box sits on its own shelf in a well-ventilated closet that is at 69-71 degrees ambient, and the Tivo box runs at 39-43 degrees, well within the operating parameters. So overheating is definitely not the issue.) Any idea of what could all of a sudden go wrong? I'm going to get a Gefen DVI Detective box, to see if that cures the problem. Right now, I kludged a solution by reinserting our video processor (which was no longer being used), and which has a pass-through DVI mode without HDCP compliance. So I get a digital picture again, but HDCP is not enabled. This may prove to be the way I'll have to end up going, if I can't find another solution. Currently this isn't a problem, since DirecTV doesn't actually use HDCP on any channels except a couple of test channels. I'm thinking that perhaps (???) the DVI blade on the TV somehow went "bad." I'm not sure how, maybe some type of surge, though all the equipment is on surge protectors, and the house itself has a whole-house surge protector, and we live in the Seattle area, which means little or no thunderstorms or lightening (and none in the last week). Therefore, just curious if anyone can come up with any possible problem, and any possible solutions that I may have overlooked! - Mike.
