Missing Secret code

Some quick and easy tips to fixing problems yourself.


• Check your antenna connection or location.
• Check your cable input.
• Check to see if the TV/VCR button on your VCR has the TV selected.

• Check your antenna direction and/or location.
• Check your cable input.
• Make sure the cable from your antenna to your TV is

properly connected.

The following may cause image problems or distortion:
Electrical appliances, powerful lights, cars, trucks; computers or
portable phones; medical equipment
• If possible increase the distance between your TV and the offending appliance.
Or shut one of them off.

• Check sound level.
• Make sure the TV sound is not muted.
• Try another channel. The problem may be the broadcast, not your TV.
• Are the Audio cables properly installed?
• Are the wires for external speakers (if you have external speakers)

properly installed?

• Make sure your speakers are turned on inthe Audio menu.
• If your audio mode is set to SAP, that channel may not have an SAP program.

• Are you in TV or cable tuning mode, and should be in the other?
• Make sure output channels on all A/V equipment are on the same channel (3 or 4).
• Check that all connections are tight.

• Is the AC power cord plugged in?
• Check that your AC power outlet works. (Test it by plugging in something

else or try another outlet.)

• Make sure your brightness and audio controls are set properly.
• Try another channel. The problem may be with the broadcast.

• Check the color settings in the Video menu.
• Try another channel. The problem may be with the broadcast.

• The Caption option may be in Text mode. Select Caption 1, or OFF

in the Captions/Text menu.

• Your program is in letterbox. This means that the shape of your TV is a

square, but the program is a rectangle. Think of the bars as empty space the
program doesn’t fill; not picture that’s blocked out. Because this format is a
direct representation of film as you see it in the movies, you are actually seeing
MORE of the program when you see those bars.

• If you forget the secret code, press the remote control Button ‘7’, ‘7’, ‘7’ and ‘7’

when the display asks you to enter the secret code.
