Troubleshooting
If you experience any difficulty with your TV, check these basic remedies before calling your service
technician.
TV will not turn on or controls don’t work
• Check to make sure it is plugged in.
• Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in something else.
• Try unplugging set for one minute, plugging it back in, and then turning it on again.
• Make sure the Front Panel Lock feature is not set.
Problems with remote
• Maybe something is between the remote and the remote sensor.
• Maybe the remote is not aimed directly at the TV's remote sensor.
• Maybe batteries in remote are weak, dead or installed incorrectly. Try replacing batteries.
Turns on or off while playing
• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and
then turn on again. If this happens frequently, the voltage in your house may be abnormally high.
• Maybe the Sleep Timer or Alarm Timer is activated.
Blank screen or black box appears on the screen
• Try another channel.
• Press RESET, in case the picture controls are set too low.
• Captioning may be turned on. Check the Closed-Caption Display control panel in the Screen menu.
No sound, picture okay
• Maybe sound is muted. Try pressing volume up button to restore sound.
No picture, no sound, but power is on
• Maybe cable/air function is in wrong position. Try another channel.
• Maybe a vacant channel is tuned. Try another channel.
Sound okay, picture poor
• Check antenna connections.
• Try adjusting sharpness function to improve weak signals.
