About once or twicw a hour the sound on the TV is interuupted for about 2 seconds. After the interuption the sound picks up but I miss what was said. This happens on all three of my TV sets. I have tried all the in house remedies. This has been going on for almost a year. Every time I look for a resolution they say it was cauised by an outage. They must have outages once or twicew every hour
