Re: LG 50LN5750-UH horizontal lines

Are there any specific guides for this issue and model? For example, cover only the first 5 pins, 6 pins, 7 pins, skip over the first one or two pins etc? I get nervous each time I do this because I'm risking damage to the connector each time I handle it...

Bad news on this repair, the line has re-appeared after about 50 hours of use. Anyone have any new suggestions? Now it seems un-watchable in this state....

I have this same model that I have put new LED strips in. The tv worked fine and clearly for about 1 hour, then the image started shifting and had lines in it. Now it is permanent. I have taken photos to demonstrate the shifting from clear, to lines and back again. My next move may be to remove all capacitors on the power board, replace them with fresh ones and try again. Unfortunately I am not sure since it may be the panel. I'm posting for professional advice before I put more time and money into this set. I have a multimeter and soldering ...

I'm a TV and electronics scavenger with soldering ability and have changed capacitors to fix approximately 5 tvs now.
