Got this Panny in which would work when the frame was twisted. Backlight fine, but picture only showed when you twisted it. Otherwise, screen would be lit, but all pixels dark.
Disappointed to find a Chi-Mei panel... and the cause of the problem? Twisting the frame was a clue. It has a bad tab bond. Applying pressure to the top left tab (from the front) brings the picture back immediately.
Sienoki is going to try the fix in this video:

Anyway build quality is very good, with top notch caps and decent build. Lots of cable grabs and tape to secure cables and keep them out of the way. It has no T-con; that's built onto the LCD panel. Since Panasonic manufacture their own IPS Alpha display panels, it's a shame that they didn't use one of those in this TV, as it would have likely lasted longer than the Chi-Mei did.
Seeing it had a Chi-Mei panel we put two and two together and thought about the LG 26LC55 we've also got... the panels are probably the same (it used a 720p Chi-Mei too)... twisted the frame on the LG and bingo! It worked... so that's two TVs in a row with bad tab bonds.
First time I've had a look at a Panasonic LCD, and I'm reasonably impressed. Definitely built well, and likely to last, if the damn LCD had...
