First of all, thanks in advance for reading this and trying to help me figure this one out. I have a 2 year old LG55LE5400. It is a 55" LED TV. A few months ago the picture would randomly cut out and white vertical lines would appear to "grow" into the screen. We would unplug the TV for a while and later come back and it would be fine. Well, yesterday it decided it is here to stay! I left it unplugged for 24 hours, tried different inputs, etc. The white lines are different in appearance, sometimes real bad, sometimes just a few. The TV still processes audio, if I have my dish on I can still hear the channels just cannot see anything but these white lines. Does anybody have any ideas? I'm assuming the tuner board is shot. Any information would be greatly appreciated

You will definately want to call LG and have them refer you to an auth. service center for warranty repair. This is either a failed scan bd or mayber even a bad plasma panel and there is nothing simple for a problem as you describe.

Bad logic board.Always replace this along with y and z sustain boards.On some LG/Zenith sets they come as a replacement part kit.

Hello,
I have been through the LG TV runaround, and I can tell you that it isn't easy. On the same unit that you are currently working on, the part numbers of the parts you received may or may not be correct. LG (Zenith) uses slightly different parts for the same model, and it really is kind of a gamble on which ones are right. They do not keep track of parts by serial number, and on different TV's of the same model, I have been through 8 control boards (on one set!), 4 sets of X and Y sus boards (on one set), digital boards, and so on and so on. The people are nice in LG's tech services, and they will admit to the fact that it may take several of the same parts to get it right.
My shop has decided not to work on LG or Zenith for this and other reasons. The turnaround time to get a TV back out of the door is ridiculously long because of the wait time with parts going back and forth.
In short, you have the right boards, but they may be the wrong boards. Maddening, isn't it?
Hope this helps you...
