SOLUTIONS
• Check your antenna connection or location.
• Check your antenna direction and/or location.
• Make sure the wire from your antenna to your Entertainment Machine 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 Entertainment Machine TM and
the offending appliance. Or shut one of them off.
• Check volume control.
• Make sure the TV is not Muted.
• Try another channel. The problem may be the broadcast, not your
Entertainment Machine TM .
• Are the Audio A/V cables properly installed?
• Are the wires for external speakers (if you have external speakers) properly installed?
• 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 plugged in?
• Check that your AC power outlet works. (Test it by plugging in something
else or try another plug.)
• Make sure your brightness and audio controls are set properly.
• Try another channel. The problem may be with the broadcast.
• Check the color control in the Video menu.
• Try another channel. The problem may be with the broadcast.
• The CC (closed caption) option may be in Text mode. Select 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. Trust us.
• Make sure the batteries are fresh and installed properly.
• Remove the batteries for 30 seconds and replace.
• Try unplugging the TV, waiting about five minutes, and then plugging it back in
and trying again.
