Question about Televison & Video
There are no user serviceable parts on these flat panel tvs.
Use your warranty if available. This is why buying the extended warranty on expensive electronics is a good policy.
Find a nearby electronics repair shop and get it checked over.

If it is affecting video only, the display's power supply
is probably at fault and without some
technical background and a couple of test instruments, you will not be able to
do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for two separate boards with mostly larger components on them; they will have ferrite core transformers on them and several larger capacitors which are cylindrical and mounted vertically to the board.
Before touching anything inside, especially on either board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.
The section most likely to fail and cause your problem will be one that you see associated more with the display than the incoming AC line; the latter is the main power supply and its failure would result in no sound or video.
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
