Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan

There are at least two issues here. First you have bad buffer boards. Second Very possibly a bad X-Main bd and P-Logic bds. Have a trained Samsung tech troubleshoot the set.

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks

The so called plastic strip is not plastic, it is call Flexible Printed circuit board made from KAPTON, they are not soldered on to the LCD panel but they are ultrasonic welded on, it is obviously that people that tell you to resolder the connection never senn or work on the LCD panel before.
I would try reseating the ribbon cables between the T-CON board and the LCD panel first. Worst case will be bad LCD panel.
