Missing part of screen on a Samsung

[Semovski]

Hi all

I have a problem with the Samsung TV. It has a dead horizontal bar on the top of the screen. It looks as 1/5 of the screen is missing. Tried to remove the tcon cable but it didnt change at all. Could it be an issue with the mother board.
When I removed the cable from the board that is getting in the tcon the line stayed for a minute and then faded

this looks like a defective LCD panel

and is not repairable

as one of the side tabs has failed.

So it is not possible to be an issue with the main board that doesnt give information somehow where to visualise the picture? I lifted the panel from the led backlight and this part seemed to be transperant where the rest was showing the snow flickles

It is not a main board fault.
Almost certainly a panel fault.

LCD works by transparent pixels appearing white, that's how brightness is modulated from the LED backlight.

Is there a way to fix it without replacing it?
How could this possibly happen?

Not repairable in most instances when it's this type of failure.
Why does it happen? Because Samsung cheap out on their panels - pieces of crap!!

Do you think they're as bad as Sharp??? I'm more scared of Sharp right now, LOL.

And hopefully, my Samsung PC monitor on one of my PCs, aren't shitty like that!

I noticed that TVs are more likely to take a shit than ad-hoc computer monitors! Why?

If it has side gate drivers or side tab drivers you could look to see it either side is melted and try pressing on each side

Re: Missing part of screen on a Samsung

Those distinct lines right underneath the white spot are a tell tale sign that the side drivers have failed on one side

Samsung are distinctly worse.

Samsung are distinctly worse.

I strongly suspected that with their TVs...
