On the center of the screen it appears a thick line aprox. every five minutes.


If your LCD still under warranty, I would suggest to get fix before it gets worse.
The screen is defective since the line only appears intermittently but you can still try replacing the T-con board first.
Most failures with lines appearing on the screen are caused by the T-con board. The Tcon board part number is:LJ94-02582B or 75014321 and you can find it here.
