I'm not sure what you mean. You can fix it often without replacing the entire LCD panel, but it's tricky.

I mean the flex cable that goes from the tcon to the top of the panel.
Do you see now ?

Thank you

Unfortunately, I would not know where to source them from. You could contact a company that may have broken apart this TV to see if they can sell you those parts.

Did you swap the two cables to see if the problem moves to the other side of the screen?

Budm,

I tried earlier but it did not move to the other side.
I noticed the small board on after the flat cable on the right is moved from its place.
Do you know what board is that ? How do we change it ?

Thank you

It is the LCD panel signal distribution board.
It cannot be replaced as it is bonded to the LCD panel itself.

Your screen has the same problem as shown in post5? Which is the same problem I had with mine. We are not getting clear answer from you, any pictures of the screen?

I will send you pic tonight.

all i can say is that I have lines on the right side, sometime it is all black but most of the time it has color of the rest of the picture.

I tried to change the tcon board but no luck.

Hi all,

So I tried to change many cable such like
1. The one that goes rom tcon to communication board (where you have USB, hmdi,...)
2. Two Small cables that goes from tcon to a small board that goes to the screen,
3. Power board.

Now the screen turns on, show the line on the right and then turns black like if thee is no power and I get the sound. Like having a radio lol

Does it sound familiar ?

Thank you for your help.

Ok I fixed the light and the picture but but the lines are still here.

Do you know what is the name of the small boards after the tcon ? Maybe it is that.

I have no other clue and any hint is welcome.

It is a bad LCD panel.
