Samsung LN52A850S LCD Vertical Line

[8cuda]

Not sure if the TV panel is causing the single thin vertical line, right down the center of the screen. After a hour or two, the vertical line goes away. Heated the T Con board, the ghosting image would go away.

I replaced the T Con board with board from ebay, cracked screen per the seller.

The vertical line still remains, but the ghosting image is gone.

Can the issue be caused by the mainboard or bonding tabs?

It looks like a panel issue.

I have the same exact TV and with the same sort of problems.
1) Ghosting appearance even after replacing the T-Con board, still looking into panel tab bonds
2) Single dead Line running right in the middle
This tells you that these particular Samsungs had a manufacturer problem that Samsung didn't want to dive into as far as recalls or even remotely to help.
So far I took it apart as far as the panel but not as deep into the removal of the panel frame to see if the tab bonds are the issue. That is next.

Most likely bad panel. Try the tab fix with pads.

Hi

Did you get this fixed as I have the exact same problem?

Thanks
