this problem is a bad panel it needs to be replaced in some cases the panel is under warranty. check your warranty.
also the E and F buffers could be at fault I would have these replaced first.

Are you using a cable box? If you are then it maybe setup incorrectly. If not, See if when you press the MENU button if the screen is filled. If it is ok then, then the plasma panel is good, but the video processing is possibly bad. Have you tried all video inputs? Let me know more info and i can assist more. Have a good one. Jay

This is a screen address failure from part of the matrix addressing. This can be caused by fair number of types of faults to cause a missing part of the addressing. You will not be able to fix this yourself.
Find out who the authorised local Samsung service is for your area. They will be able to give you an estimate.

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
Eric

There is no color wheel or lamp in a plasma TV.
The problem is most likely the lower buffer " E ". It controls the right side of the screen. Worse case, it could be the Logic Board. A Service Manual for you TV will have the part number for replacement. The manual will also give you procedures on how to replace the part yourself. The service Manual for your TV can be found over the internet for less than $20. This is the best do it yourself manual you need for repairs on your TV. :)
