TV not responding properly to remote or direct input
My TV has gone haywire. Suddenly the volume control from the remote started working intermittently, and then the volume shot all the way up without the volume button being touched. I couldn't adjust the volume using the buttons on the TV either. It would work fine one minute, then go haywire the next. Also, it won't let me change the source using the Input button on the remote and I can't shut the power off using the remote. The TV is hooked up to a cable box and a TiVo. Both those remotes can control the TV and are experiencing the same problems. I can turn the TV on and off using the button on the TV, but that's about it. Very bizarre behavior. Can you help?

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.
