Since a week ago, my TV starts to behave strange. When I turn on TV, the main picture has lots of little horizontal rectangular boxes stage diagonally either from top left to lower right or from top right to lower left with three different colors, white, pink, and/or green. In addition, the picture distorted and has memorized about 2-3 seconds. I noticed this only happens on analog channels (digital channels are still clear in main window). However, picture-in-picture is always clear on both analog and digital channels. When the problem happens; if I unplug power cord for about 5 minutes and plug power cord back, TV becomes normal for a few days. As the problem happens more frequently, it only last a couple days now. I also tried to direct feed cable signal into TV and Cable to VCR then TV, they all have the same problem. Contact Samsung with no help. Below is the picture. Does anyone know what the problem is? Thanks!
