Re: LG 47LM640T 3D Smart LED TV thin horizontal lines

Hi. Back with the problem. I heated first the mainboard . No effect at all. I ordered another main board and just replaced it , didn't cured the problem. What is left are the 2 pcb s under the screen which are kind of irreplaceable because are together with the screen. They've got though some small resistors Capacitors and diods I think. Any chance someone can have a play on them? Or is just waste of time. Would any magnetic field from a external hdd affect them? I had my external drive under the tv for few hours.

Hi. My tv 47 lm640t-za is developing the same problem with horizontal line. Any solutions from someone who sort it out? Thank you. The lines on my tv are more towards the left side of the tv. The right side it's not so bad....
