Visio 32L color goes bad with ghost images after...

Question

We have had no problems with our tv since we purchased it a bit over a year ago. Recently after it is on for a while the picture goes bad with weird color and ghost images. If you shut it off for about 2-3 minutes and turn it back on it will work fine for about the same time period and then go bad again. If you shut if off for only a minute it will not return to a good image. Almost like the power has to bleed off everything before it works right again. Any ideas?
