Re: Samsung LN52A530

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.

Re: Samsung LN52A530

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

Re: Samsung LN52A530

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

Re: Samsung LN52A530

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

Re: Samsung LN52A530

There is two of those board.
What else could it be ? This is driving me nuts not to found the root cause.
I will not give up until I found the root cause

Re: Samsung LN52A530

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?

Re: Samsung LN52A530

sorry if this is not clear.
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.

Re: Samsung LN52A530

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.

Re: Samsung LN52A530

Sounds like 2 seconds to black, can you see the backlight working in a dark room?

Re: Samsung LN52A530

No it does not shows.

Thank you so much.

Re: Samsung LN52A530

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.

Re: Samsung LN52A530

It is a bad LCD panel.
Fixable, though: https://www.badcaps.net/forum/showthread.php?t=25371
