Troubleshooting

Most problems you encounter with your TV can be corrected by consulting the following
troubleshooting list.
TV Problems
The 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 another device.
• The side panel controls may be locked (disabled). Use the remote control to unlock the side panel
controls.
• Select the Button Block feature on the Parental Control menu and press OK to uncheck the box.
There is no picture and no sound but the TV is on.
• You may be tuned to an input with no component connected to it. If you're trying to view a
connected component, press INPUT until the picture from that component appears.
• The Signal Type option may be set incorrectly. Go to page 23 for detailed instructions.
• The channel may be blank. Try changing channels.
• If you're watching your VCR and it's connected with coaxial cable to the ANTENNA/CABLE 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 make sure the TV/VCR button on the VCR is in the correct mode (press the TV/VCR
button on your VCR).
The sound is fine, but the picture is poor quality.
• If you're getting a black and white picture from a component 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 on the side or back of your TV; three video cables or bundled
component video cables (red, blue, and green) connect to the corresponding COMPONENT INPUT
jacks on the back of your TV.
• Check the antenna connections. Make sure all of the cables are firmly connected to the jacks.
• Try adjusting the sharpness function to improve weak signals. Go to page 23 for more instructions.
There is no sound, but the picture is fine
• The sound might be muted. Try pressing the volume up button to restore sound.
• If using DVI 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 22 for more information.
• If your audio source has only one jack or is a (mono) audio source, make sure you have plugged
the connection into the L AUDIO INPUT jack on the TV.
The screen is blank.
• Check your connections. If you used yellow, red, and white cables to connect, make sure they're
connected to the red, white, and yellow AUDIO/VIDEO INPUT jacks on the side or back of the TV.
• If you're trying to watch something that's playing on a component connected to the TV (like a DVD),
press INPUT until you get to the correct video input channel.
• Make sure the component connected to the TV is turned on.
• Try another channel.
