LG 60PZ550 plasma black line in red field

[Tvbob]

Hello fellow enthusiasts..Not doing much any more as i am getting old.
I ran a cross a LG 60pz550 plasma with a bad main video, tuner, input board.. I jumper out the test pattern pins on the logic board and I have a vertical line on the red field.. should i try a buffer board (ebr71726401) or do the panels fail in these sets.I know the main video board will have to be sent out for repair if the buffer take care of the vertical line.. Thanks

Bad panel, not repairable, sorry.

Not a bad panel but bad connection on the lower buffer connections
Try tapping the lower buffer connector located where the line appears when its on

No this is definitely a bad panel if it is only one line, because it's at the driver point.
You might be able to momentarily fix it by tapping on the right point but short of replacing the driver chip, I think you're out of luck.

I did not notice the line until after I removed and reinstalled the Z sustain board to resolder the inductor coils..Its a sharp thin black line in the red test field, A dull black line in the blue field, NO line in the green or white field..Also has any one connected these panels to any of the cheap Chinese video boards out there in lieu of repairing the main video board.Thanks guys

The cheap Chinese universal Main Bds. are for LCD tvs and not PLASMA tvs
