• Make sure that the power cord
is connected to your TV and a
power outlet.

are connected securely to the
back of your TV.
• Adjust the contrast and
brightness.
• Make sure that the correct
video mode is selected.
• Make sure that the incoming
signal is compatible.
• Make sure the antenna is
connected correctly.

settings. Some TEXT modes

muted.
• Make sure that the correct

• Adjust the contrast, color, and
brightness settings.

too bright. Light reflecting off
the screen can make the picture
difficult to see.

camcorder is connected while
another connected device is
turned on, the picture may be
poor. Turn off one or more
devices.
• Your TV may be too close to
another electrical device, such
as a hair dryer or neon light.
Turn off the device or move
your TV.
• This may be caused by
obstructions to the antenna,
such as high-rise buildings or
hills. Use of a highly directional
antenna may improve the
picture quality.
• Press the TV button.
• Replace the batteries. Make
sure that the + and – symbols
on the batteries align with the +
and – symbols in the battery
compartment.
• Clean the remote sensor on the
front of your TV.

may interfere with the remote
control signal. Turn off the light
or move your TV.
