I have three ceiling fans installed on the same circuit in a new house. Whenever I turn the fans off, it causes the T.V. To black out for a few seconds. It does not happen when I turn it on. I have checked all the wiring from the fan to the house wiring, and all of the outlets to make sure everything was tight, and wired properly. Any idea on what could cause this? I also plugged the T.V. Into two other circuits in the house with an extension cord, and it is still happening. None of the other T.V.'s in the house do this, and several of the T.V.'s are same model. We also tried moving other T.V.'s to that room, and had the same problem?

Try to get a power center, is a box you plug into the outlet, and the box has outlets that you connect your TV too, it would protect your TV from spikes and it might just fix your problem.

Or if you have Verizon fioz losing signal is normal...
