So I sat down to watch Sunday night football. Every 1-3 minutes the screen would go green, and cut out to black then come back on. Every 5-7 minutes the screen would just go black, and every 9-10 minutes the whole thing would cut out and I would get snow for a good 10 seconds. This isn't even counting the constant pixelation. I came over from fios due to a move, is this really what I have to look forward to with Comcast HD?
There is no issue with your TV as any problem with your picture screen would have been completely different than what you have reported. It could be overheating of the Box, or just an electronic or hard drive failing or even an HDMI incompatibility issue. Restarting the box or TV usually does the trick.
