Now, getting back to the problem at hand, what graphics cards is everyone using? I've got a GeForce 9600 GTO and it seems others are using nVidia cards too. When I brought my set into BestBuy they hooked it up to one of their computers to try to replicate the problem. They said the TV powered on just fine. I asked what they had in their computers and they said some kind of ATI card.
Is anyone with this problem using an ATI card? Is everyone using the latest graphics drivers? I don't want to have to get a new card but it would be interesting to know why ATI cards work (if that is indeed universal).
Talking on my own to a Panasonic developer, who in turn went to his engineers and replicated the issue I was having at least. I don't believe it has anything to do with the video card on the PC, however for the sake of argument, I'm using an 8800GTX like I mentioned earlier.
The thing that PC videos cards apparently do is send out a voltage signal like another user posted. This was confirmed by the people I spoke with at Panasonic. After a little bit of troubleshooting there are a few ways to get around it at least on my set (850U).
HDMI 1-3 - In back
HDMI 4 - In front
The only port effected by this extraneous voltage signal is HDMI 1. Seems that it is a hardware issue. Not sure why they have a port that is built differently than the other ports so I dunno.
The other thing you can try is once the TV is on, if you have a TV where only the front port works, and you'd rather use a back port is the following:
Assuming, you have it powered on and functioning correctly. Prior to turning it off, turn the input to a different input, perhaps the component or TV input. The developer I spoke with, mentioned this as a possible work around w/o having to plug into a front port, if all back ports produced the same error. He said, that you either have to have the PC off when you turn the TV on (which was unacceptable for me since the PC runs 24/7) or try what I just mentioned. I tried HDMI input 2 first and that was successful so never got around to testing this method.
Unfortunately this is most certainly a Panasonic issue and nothing else. Maybe they were trying to save a few $ to sell the set cheaper by not including some components they didn't think were necessary. Well, seems like in small cases like what we have, they are necessary.
I don't have nice and concise quotes to post as all correspondence was over the phone.
Best of luck.
