Lcd TV: crack or mainboard damage?

post #1 of 6
Thread Starter 
My grandparents TV does this:

What could it be, i can't find any visual cracks frown.gif
Would it be internal crack or mainboard damage?

Looks like the board failed.

Does it do it while using other inputs, including the analog ones?

Yes, at every input,
HDMI, Analog, VGA, SCART, everything.

If you're lucky there is a separate board with the inputs and a processing chip that connects to the mainboard. You might be able to find a used one for cheap on our favorite auction site. I had to replace the video input board on a Samsung monitor not long ago for video corruption reasons, though in my scenario it only failed on analog inputs.

EDIT: With no input at all and the onscreen menu displayed, does it still occur? If so, it's probably the mainboard and not the video input board (if separate)

I just found this while taking a look at the screen with my smartphone's LED light.
But its very smooth and curving, it starts at he bottom right about 5cm from the bottom, it enters the screen, then smoothly curves and goed up to like almost top of the screen.
But the line is ultra smooth, i rather think its a hair then a crack. The line goes left and right and not in a straight line.
