Everytime something like the microwave door shuts, or we turn on or off the fan in the bathroom, its like it interfers with the tvs. Not anything else, that I know of really, but I can be watching tv, then my Mom shut the door on the microwave, or turn on/off the fan in the bathrooms, and I will see just a quick signal interferance with my tv. It is the same way with all the tvs, its not damaging anything that I know of, but what is causing it, and is it actually something serious that needs to be looked into? Also my Dad and his friend who is basically an electrician looked at the wiring in the house, and tested the wires and outlets all throughout the house a couple years ago when this first started happening, and they found nothing. We had another problem with the breaker constantly being tripped, and they did find the problem with that, I dont know what it was, but they fixed that by putting in a new breaker box, and re wiring some things. Any ideas?
