I've had my S3 since about when they were launched. A few months ago it "died" so I replaced all the PS capacitors and that brought it back to life. It's been working great since then until the last several days. I'll be watching a recorded program (or live TV) and the screen will suddenly go to black. The program will continue to play. After a few second (up to 20 or 30 seconds sometimes) the screen will come back. This tends to repeat frequently once it starts. I have power cycled the TV, which appears to fix it, but only temporarily (but it could be unrelated). I have a Sharp Aquos LC37D64U 37-Inch 1080p LCD HDTV I bought in 2008 which has been great since then as well. So how do I figure out of it's the TV or the Tivo causing the problem? I tried changing HDMI inputs on the TV, and the same thing persists. I don't have any other HDMI sources to test the TV. Is this a known issue with Tivos, or is it more likely the TV? Thanks.
