PN50C550 vertical colored lines

Is this as bad as it looks like?

Anything I can test? The lines are on top of the menu too...

Bad plasma panel.

Bad plasma panel.

I assume you mean the driver ICs on the the flatcables going from X-board to the panel?

Yes not fixable as they are bonded to the panel.

What does it take to repair this?

Isn't this stuff similar to what they sell here? :http://www.iccfl.com/product_info.php?products_id=18483

I guess the "not fixable" isn't the answer you want. You can try some thermal pads "pressuring" on the bond area to see if some pressuring changes / helps the problem.

The issue with trying to replace the bonded flex cable is that the alignment is a significant factor along with the bonding such that "field replacement" is not "practical". Of course, you have to find the exact replacement flex tab cables.
Since you likely have a bad panel and nothing to loose other than some time and maybe a "dollar or two", do your own "experiment"... who knows you might be successful. I am sure you will be a "forum hero" thereafter and everyone will be extremely interested in your achievement since this type of failure (flex tab issue) kills a lot of panels.

I think I'll jump in here. I agree with paulstef. I'm going to try replacing a tab ribbon cable bond with one from a set with a broken screen.

I dont thinks that possible not on the vertical hight drivers. I however have been able to do it on the horizontal tabs well I repaired the traces in it.
