Why does my TV keep changing channels by itself?
One of the most common causes for a television in your home to change channels on its own is a neighbor who owns a similar model of television. … If your TV moves out of range, or if the remote receiver is simply pointed in a different direction, this can stop the problem.
How do I get my TV to stop changing channels?
Unstick the stuck button
Maybe a channel-switching button (e.g. the channel + or – buttons or a channel-number button) on the remote control or on the TV itself is stuck. All you need to do is to unstick the stuck button and the TV will stop changing channels by itself.
