Issue with channel 1434 (TBS) cutting in and out (pixelated) most days of the week. Problem not always occurring, but it happens more often than not throughout the week now. Image and sound comes and goes (broadcast freezes and unfreezes about every 2-3 seconds constantly for a day or two and then doesn't happen for a day or two. This has been occurring for many months now and problem is getting worse. I have called support twice with no resolution either time. The problem occurs on all tvs in the house. Not a physical hdmi cable issue. Problem only occurs (to my knowledge) on this one channel.
