I had this exact same thing happen to me about 2 months ago on my 50"
LG plasma. Although mine was saying that it was reading a corrupt EDID.
I tried several cables and even hooked up another computer to make
sure it wasn't the cable or the video card and so it remains a problem
and I think it's with the plasma :-(

The solution I found was to get the EDID on the 'net and configure the
nvidia driver (through xorg.conf) to read from a file.

So, I'd try reading the EDID from the TV with another computer/video card
and saving it out and using that. If you can't read the EDID with another
machine, try another cable or look on the net for an EDID that you could
use.
