My mother's was doing the same thing (purchased 2008). Put up with it about 6 months and took it to a repair shop. Bottom line - the display panel has a flaw in and will cost more to replace than the tv cost. See about it now it yours is still under warranty.

SOURCE: I have a SANYO DP46848,
This is likely a problem with your TCON circuit board inside the back of the tv.
The TCon board usually has 2 (or 4) very thin ribbon like cables running from connectors on the board to the actual LCD screen panel. Each ribbon controls one half (or one quarter) of the screen. If you are lucky, it's possible one of the ribbons came loose or is not making proper electrical contact with the connector on the TCON board.
If your tv is out of warranty and you are comfortable working safely with electronics then you may be able to repair this yourself with a few hours of screwdriver work. The ribbons may just need to be reseated in the little flip up connectors, or you may have to clean the copper at the tips of the ribbons gently with a pencil eraser to remove any oxidation.
If you are unlucky enough to have a bad TCON board or are not comfortable disassembling your tv yourself then you can bring it in to the shop and they can probably repair it for less than $150.
Good luck and please post back with how you make out.

Solved: Over the course of time, the cheap plastic frame and stand starts to put uneven pressure on the LCD causing it to malfunction. I guessing this could be heat related. Definitely a design flaw. Remove the bottom of the stand and very slightly loosed the small screws around the back of the frame allowing the LCD to have some wiggle room. After I did this, it worked. It will still misbehave if you stress the LCD, but normally, it shouldn't. I am going to try to mount the TV using the rear VESA mounts & see if it will still work.
