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 Block Buttons 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 18 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.
• If you’re getting no picture from a component you’ve connected to your TV, you might have your video
cable connected to the VIDeO OUTPUT jack on the back of your TV. These jacks are used to connect
recording devices. A yellow video cable connects to the yellow VIDeO InPUT jack on the side or 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 36 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, 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 37 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.
