For several weeks, the sound will either break up or cut off on Comcast Cable Channel 433, CBS HD.
The sound will come back on in one or two minutes, but this happens at least once per hour and more often, once per half hour. How can I get Comcast to fix this problem?
sounds like a signal issue at your home, You should schedule a tech visit to go over your set up. A signal issue can present itself on just one channel.
