Since installing Fios TV my family room TV will come on to channel 10 (it's on channel 3 to receive signal when turned off) every evening at 8:55 p.m. Any idea how to fix it?
If your TV is turning on and changing to another channel off of the 3 its always set at, this is something programmed inside the TV to be causing this. You would need to go through your TV's menu to turn this option off. Not knowing anything about your TV brand I can not provide you a step by step on how to do this.
