New Request for Help!
Update after 4 months:
I was incredibly lucky recently and found someone who was giving away this model tv only two towns away from me. He had broken the screen while moving and just wanted to get rid of it. I took it home and stripped everything potentially useful out of it. All this after months of being completely unable to find a DG board online.
But most importantly I installed the newly acquired DG board in my tv (along with the "new" ribbon cables) and it works! I've probably put about 20 hours on it since. [U]HOWEVER[/U],...

Re: Panasonic TH-50PX500U plasma 50" TV with scrambled screen
I ordered a DG board and installed it. Unfortunately, it did not solve the problem, and instead caused the tv to not turn on at all. When I plug the tv in, the power light flashes red four times. Re-installing the old board brings back the original problem. The boards have the same parts number (TNPA3625 AB) but the stamped number (order number?) is EN5602C on the new board but EN5603C on the old board. Is that the difference that is making the replacement board not work? The eBay seller claimed it was tested and...

Here you go. But I emphasize that the patterns do not look like this to the eye. All are rich in color with sharp edges and smooth gradients, with no obvious defect. Other than the moving bar test I described above. Thanks for the input....

Did the test and almost everything looked fine. The photos I took made the patterns look messed up when they really weren't. The only thing that stood out to me was the test that featured a vertical white bar moving horizontally from left to right. As you can see in the attached photo, it was a bit jagged. As it moved across the screen, the spots where the bar was shifted moved consistently toward the top of the screen. Dunno if that is the way it's supposed to be....

Thanks for the reply. I'll see if anyone else has opinions on this, but in the meantime I'll pull out the D board to take a look at it and get the part number. Do you think this issue could be a more serious version of [URL="https://www.badcaps.net/forum/showthread.php?t=38592"]this guy's problem[/URL]?Re: Panasonic TH-50PX500U plasma 50" TV with scrambled screen

I don't know how to identify if it has a separate control board or not. What would I look for? This is my first time opening up a flat panel tv. I'm attaching a picture with the back casing removed, if that helps. Thanks...

Panasonic TH-50PX500U plasma 50" TV with scrambled screen
Hey everybody,
I picked up a Panasonic TH-50PX500U plasma tv for free the other day. I was told it had lines going across the screen, so I did research prior to picking it up and thought it would be an easy fix. Turns out that it has more serious problems. As you can see in the photos I've provided, the screen shows a sort of multi-colored scramble in vertical lines. I don't really know what to call this, so search hasn't been very productive.
It is a strange problem to me because it happens on all inputs, but some things show up fine. I've hooked it up to my cable box via...
