Vertical color lines at startup of lg 37le4500.za
Hello,
I have an LG 37inch LED LCD TV (model 37le4500.za) which worked perfectly for 4 years but now every time I switch it on, the screen becomes full of color vertical lines (some are 1 pixel width other are wider).
The lines are changing with the signal.
After 15-30 minutes of lines, the image appears correctly. But now it may take hours to appear (maybe because now the weather is colder).
After making some tests heating the T-CON board, I decided to buy a T-CON card for my TV, but I discovered the T-CON is not the problem. Why it's not the problem:
When I installed the new T-CON there were lines, and when the image appeared after 15 minutes, I quickly put the old T-CON and the image was still ok.
I have seen other TVs like mine with the exact same problem.
What is wrong in my TV?
Some pictures of the TV boards:
Thanks,
Jordi.
Is this a good question?

Post some pictures of your different boards, i.e. power board etc. so we can see what you see. Sounds like either bad caps or bad transistor.
