Samsung ps50b451b2w vertical lines on screen

[Mr_Bodgit]

Picked up this 50" plasma tv today for nowt, but right hand side of the screen has 3 vertical bars about 3" wide 3" apart from each other all the way from top to bottom, first one is all different coloured lines, next ones black with a green line down it and last one (very edge of screen) is just white, is it most likely the tcon card, a bad connection on ribbon to the actuall screen or is it just shot and only worth breaking for parts?

Run the internal test patterns via the jumper on the control board. Long shot but may as well try.

Cheers for the replies guys, I'll have a look this week if I get chance, may break it for boards tbh

Re: Samsung ps50b451b2w vertical lines on screen

Found the problem, the far right strip of lines are because the actual first vertical screen connection has come away/unglued and pushed back from the bottom circuit board all together (labled 50u1p logic buffer_e), as for the other two rows (multicoloured lines) I'm guessing it's a fault with the same board or the logic board with the lines being in 3" wide strips

Can the logic buffer_e board with the glued screen connections be replace with them being glued or should I just break it for parts as it all works bar the screens lines

You could always try 3m 3703 conductive tape.

9705 seems to be the right number as that other number comes up with a box tape
