The sound on my television keeps going out. I use Time-Warner Cable.This usually happens during the day.It happens for seconds at a time, sometimes the sound is out for almost a minute. Could this be happening because of a nearby computer or something else that sort of sucks out the sound from my T.V.? Everybody in this building is sharing the main cable wires i.e. legally. So can this be happening because we are all sharing the transmission? Thanks!
