TV responds to on-off, channel & volume changing buttons, but nothing else on remote. Screen is dark, but the station and show listing appear at bottom. Sound of show works, but no picture.


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.
