PN50A450P1D Thin(1 pixel wide), colored vertical lines - only right half of screen

[gobblebox]

I just picked up This 50" Samsung Plasma TV from my brother-in-law, thinking that it would be a simple repair. After reading several threads, and doing a lot of research, I'm lead to believe it could be one of 3 things (or sadly a bad panel): a loose ribbon cable, Y (why not X, since the lines are spaced along the x-axis?) Buffer Board, or the Timing Control board. The vertical lines are only 1 pixel wide and are randomly spaced out, but only on the right half of the screen. They consist of magenta, cyan, and green. Would anyone have any ideas, or be able to provide a little more insight to narrow it down to one of these replacements?

Almost certainly a bad panel if they are randomly spread out, this is a common issue with this model of Samsung plasma.

Hi Tom66, what do you mean a bad panel? Is it the main board or the t-con board? Thanks

I mean the plasma display panel itself has failed, more specifically the bonded chips at the bottom of the panel, unfortunately this will not be economic to fix in most cases as a new screen will exceed the value of the TV.

Newbie here.
If the same type of symptom (thin vertical "noisy?" Colored lines) were to be evenly bad across the whole screen, would that also indicate a bad panel? (failed, imbedded chips at the bottom?)
