I have a WS 65713. Just started that when i turn the TV on, the picutre is wavy for about 30 seconds at most and looks great afterwards. TV will work flawless for about an hour or so, and then the picture and sound will shut off, all the while the TV is still powered up. I can then just turn the TV off and back on immediately and the picture and sound are fine for another hour or so and the same process happens again. This will also happen when watching a DVD. Any clues if it is a capacitor issue on the DM board? I had the blinking light issue 4 years ago and that was fixed but now this issue is happening and i was wondering if it is another capacitor issue but different ones or completely separate issue.
