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 TV panel controls may be locked (disabled). Use the remote control to unlock the TV 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.
• The channel may be blank. Try changing channels.
• If you’re watching your VCR and it’s connected with coaxial cable to the
ANT/CABLE/SAT IN 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).

• 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.

INPUT until you get to the correct video input channel.
