When I'm watching TV a channel will become garbled. Mostly sound but some picture. I will change to another channel and it is playing perfectly. I'll go to another channel and its messed up to. There doesn't seem to be any trend to what channels are messed up or when. It comes and goes. I have tried to use the fix TV issues on the menu at least a dozen times and it seems to work for that channels for a short time, but then it comes back later. I have checked the connections and they are all tight as they have been for many years. I've sut off and restated all verizon equipment except ONT. The support and ask verizon was of no help at all. I'm so tired of turning on something I dvr'ed and find it completely unwatchable. Anyone point me into something else to try
