For anyone having trouble with a Samsung television, using the Electronic Manual stored on the television can help correct issues. A cable signal or malfunctioning piece of equipment such as a cable box or recording device may cause some television issues.
To access the on-screen manual for a Samsung television, press the Menu/123 key on the remote, and select Support from the menu. From the Support menu, select E-Manual. This opens the user guide on the television screen. From the screen, select the issue that the television is having.
Sometimes, the television simply needs reset. To allow the TV to rest, turn it off, unplug it for 10 minutes, and then plug it back in, and turn it back on.
