I have a Roku TV model TCL 32S3750. The TV can display antenna TV stations and change them with the remote, but for cable the TV is stuck on just one channel. When I try enter another channel on the remote or try to raise the channel guide nothing happens.
It seems my question did not invite answers. The Roku TV works with streaming media and antenna TV, but for cable is stuck on one channel. It did not help to replace remote batteries. The wireless connection is OK and I reset the TV to its factory settings. Is my TV simply broken and thus should be replaced?
