I have a SANYO DP46848, 46 inch flat screen hdtv purchased about 2 - 3 years ago. The screen goes dark on the left side (top .25% is ok). It sometimes fixes itself after an hour or so. Sometimes you can fix it by placing your hand on the dark spot for 10-15 seconds. There is a thin horizontal line about 1/4th of the way down from the top with the top of line ok when the bottom of line area goes dark. LCD Controller? or Main Board? or Power Supply or the Panel itself? I have a picture if that
