Facing TV Problems? Ask a TV Technician.
Welcome to the site! I'm Dan. Please reply back so I know you're here. Also, are you with the unit now?
OK, good. What types of audio/video devices are connected to the TV? Cable box, DVD player, game console, etc.? Whatever is connected, can you check each of those inputs to see if the same thing happens with each?
OK I'll be here.
