The display screen is made of a matrix of elements connected to cables
along the side and top. On your unit, some of these many, tiny
connections are making contact intermittantly thus losing the elements
in that area. These contacts are held in place with just pressure and
if that is disturbed, you lose that line of elements. Try squeezing the
cabinet of the TV on the outside at the top in the area of the loss and
see if that makes a difference. May have to go inside and see if the
contact assembly is disturbed or warped or something.
Hope ya fix it!

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;
