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

This most likely a problem with the T-CON board.
If this set is under warranty you should return it to get it repaired/replaced by the seller.
IF YOU KNOW HOW TO WORK WITH ELECTRONICS REPAIR(board replacement ) or have a friend with knowledge/skill you can fix it.
Sometimes due to heating/cooling or contamination the connection pins on the T-CON board and cables do not make good contacts. The T-CON board is located in the center of the set.
After taking off the back cover and shield over the T-CON board carefully remove the flat cables connected to the T-CON board. I believe there are 4. The connectors have a lip on them to hold the cables so be careful.
Now reconnect the cables. Recheck the display now. If it has not corrected you can disconnect and reconnect again.
The very first solution I entered on fixya.com had essentially this same problem and solution.
If this does not solve the problem you can replace the T-CON board.
The T-CON board look something like;
