We have DirecTV connected to a Sony TV. Occasionally, the picture will flicker slightly, the colors will get pale and after a few seconds everything is normal again. The odd thing is that it happens only on the local channels (lower channel numbers). We swapped the Sony set for a different set and did not experience the problem, so we thought the Sony was shot and bought a new set, which was also a Sony. Same problem with the new set. I have checked all the cable connections and they seem ok, the cable itself seems to be intact. I wonder if anyone has experienced anything like this, or might have some advice aside from paying somebody to come out and take a look.
