We recently moved into a new to us home. The home is 5 years old. We have had Dish satellite tv installed. In the master bedroom the installers had to use a baluns via Cat 5 wire to get the signal to the tv. Now if we turn the light switch or switch for the fan on or off the satellite signal on the tv goes off for approximately 2 seconds then returns. Same thing happens when a small fridge in the master bedroom cycles off. I thought at first it was the tv turning off and back on but I played a movie via dvd player and could not replicate the problem. Any ideas? While not horrible it is kind of annoying.
