Troubleshooting
Most problems you encounter with your TV can be corrected by consulting the following troubleshooting list.
TV Problems
TV won’t turn on
• Make sure the TV is plugged in.
• Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in something else.
No picture, no sound but TV is on
• You might be tuned to an input with no device connected to it to view. If you're trying to view a connected device,
press INPUT and choose the option that matches the input of the device you connected.
• Maybe the Signal Source option is set incorrectly. Go to page 15 for detailed instructions.
• The channel might be blank — change channels.
• If you’re watching your VCR and it’s connected with coaxial cable to the ANTENNA/CABLE INPUT jack, tune the TV
to channel 3 or 4 (whichever channel is selected on the 3/4 switch on the back of your VCR). Also check to make
sure the TV/VCR button on the VCR is in the correct mode (press the TV/VCR button on your VCR).
Sound okay, picture poor
• If you're getting a black and white picture from a device you've connected to your TV, you might have your video
cables connected to the wrong jacks. A yellow Video cable connects to the yellow VIDEO input jack; three yellow
video cables or bundled component video cables (red, blue, and green) connect to the COMPONENT INPUT jacks
on the back of your TV.
• Check antenna connections. Make sure all of the cables are fi rmly connected to the jacks.
• Try adjusting sharpness function to improve weak signals. Go to page 25 for more instructions.
No sound, picture okay
• Maybe the sound is muted. Try pressing the volume up button to restore sound.
• If using S-Video or Y, PB, PR, remember to also connect the device’s left and right audio output jacks to the TV’s L
and R Audio Input jacks.
• The sound settings may not be set correctly. Go to page 26 for more information.
• The internal speakers might be turned off. Go to page 26 for more information.
Blank screen
• If you're trying to watch something that's playing on a device connected to the TV (like a DVD), press INPUT and
choose the option that matches the input where you connected the DVD.
• Press the WATCH TV button.
• Make sure the device connected to the TV is turned on.
• Try another channel.
Buttons don’t work
• Unplug the TV for ten minutes and then plug it back in. Turn the TV on and try again.
TV turns off unexpectedly
• Sleep timer may have been activated. Go to page 27 for instructions.
• 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 or low.
• Unplug. Wait ten minutes. Plug in again.
