I have 5 TV's with the cable boxes being run via HDMI from one room in the basement. This is new construction. The TV's blink off when the wall switch for the fans is turned on. The fans are not on the same circuit. Also I have found that when I turn on the light in my master bath it makes the TV blink off in the master bedroom. Then the signal returns after a second. Does anyone know how to stop this from happening?

Do the power lights on the TVs go off? What if you are using an alternate input? Say you hooked a laptop up to the TV locally? Does it still happen? We need to determine if it is a signal interruption problem or a power interruption problem.

My GUESS is it is a signal interruption problem. How is the signal getting from the basement? Long HDMI cables or some kind of HDMI extender?
