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.
• Something might be wrong with your remote control. Press
the POWER button on the front of the TV. If the TV turns
on, check the remote control.
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 or Wake-up Timer is activated.
Blank screen or black box appears on the screen
• Try another channel.
• Press PRESETS, in case the picture controls are set too low.
• Closed Captions may be turned on. Check the Closed-
Caption Display control panel in the Screen menu.
Can’t select a certain channel
• Channel may be blocked or not approved through
Parental Controls.
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.
Parental Controls won’t let me watch a program even though it’s
not rated as violent
• Maybe you have blocked a movie with a rating of “Not
Rated” or an “unrated” TV program. Go to page 15 for
more instructions.
