Panasonic Plasma 42" - HELP

[BILLWEIBLE]

I had an issue with a stripe approx. 2" wide running vertical in very center of screen from top to bottom. Figured it was the C1 board because that's where the ribbon from the screen controlling that area plugs in. I removed the C1 board and tried reflowing the solder using the oven method, I know, dumb, dumb thing to do.
When I reinstalled baked C1 board the entire right side of TV stays black. I ordered a new C1 board and after installing I have the same thing, right side is black with exception of a few vertical stripes near right side of screen showing a type of color band. Starting to think what else could be causing it. I've cleaned ribbon from C2 board and from video out board that plug in to C1 but still just black on right side. Could be the origina lC1 wasn't to blame for black on right side.
I'm stumped....

Pictures of your fault.

Most likely bad tab bonds - Not fixable

How could just removing and reinserting the C1 board cause the TABs to go bad. I will attach photos ASAP when I get home. Ever since I removed C1 board and then reinserted it and also when installing a new C1 board I get the same thing, half the screen (from the C1 board) is just black. A few places I have a color banded stripe about 2" wide running vertical from top to bottom on the side that's black.
All I did was replace a board, how could tabs go bad when it was working almost perfect before board swap, I was just starting to get a stripe 2" wide directly in the center running vertical from top to bottom, that's why i replaced the C1 board in the first place. Ever since I removed original C1 and with new C1 it just remains black on right side with a few small color bands in 2" stripes from top to bottom. The left side displays perfectly.

Nah--There's a Chip ON the Mylar film that fails on these panasonics (and other sets)
42PX60....??

Those tabs are VERY delicate, and can easily be damaged, just a single track broken on them will cause serious issues.

Normal cause of a black bar down screen is the COF Chip ON the Mylar tab (chip is on the ally plate screwed to chassis) from Screen Glass to the Lower PCB's....

These Cannot be replaced, so the set is toast sorry to say.

You had the issue start before the board swap... It was already failing.. It has now just completely failed on that side of the set.
