Please excuse any lack of technical language or any info accidentally left out, I'm not real technologically inclined.

I've got a Panasonic HD-ready, flat screen CRT that's maybe 5-10 years old. It worked fine last night. I turned it on this morning, and I get no picture. I've got sound, and I can change the channel, but nothing but black on the screen. I can also change inputs and go from cable to DVD to whatever, but still the screen doesn't change.

Any idea on what's wrong and how to fix it? I thought everything was solid-state these days, but from a little reading it seems like there might be tubes in there that burned out. But I could be wrong. google isn't much help as it seems like most of the hits it came back with deal with problems when hooking up to a computer or other device, not cases where its fine one day and poops out the next.

Thanks for any help.

Just to update, a repair guy came over and said it was the vertical driver or horizontal driver or something else (he was foreign so a bit hard to understand) that had a bad connection. Took an hour, a lot of soldering, and about $200 to fix.
