Hi I have an LG 42LG-3000 TV when I put it on the white screen, cropped up and down and on both sides. As it warms up, the blank screen without image is filled. Sound good. What can be?

Hi, I have reviewed T-con module, flex cable welding and contacts and nothing, everything remains the same. Yes, I noticed that when I force the screen a little, the image appears. This leads me to believe that everything could be a problem on the screen itself.

it can be a false contact in the flexible ones, I leave you a video, nothing is understood but on the end it looks like it is diagnosed and how it resolves

but try this practice
I will indicate a practice, always very carefully and fiddles with the unplugged TV
try disconnecting one of the two flexes that go from the t-con to the display and test if you have an image in the middle of the screen, if this does not happen connect it (eye, well connected) and disconnect the other and try again, if you see image in the middle of the screen is the bad display, I can indicate a practice to solve it in the best case

Hello Iglesilu, welcome, by chance you have an ace15 on the t-con board, touch it to see if it overheats ...

This fault can be corrected by cleaning the contacts of the flex cable lvds and cleaning the connectors of the tcont and reviews the welds of the earths of the connector of the tcont and you solve many luck
