Cautions regarding use in high and low temperature environments
When the unit is used in a low temperature space (e.g. room, office), the picture
may leave trails or appear slightly delayed. This is not a malfunction, and the unit will
recover when the temperature returns to normal.
Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location
exposed to direct sunlight or near a heater, as this may cause the cabinet to deform
and the Liquid Crystal panel to malfunction.
Storage temperature: -4°F to +140°F (-20°C to +60°C)

Adjust the picture tone. (See page 32.)
Is the room too bright? The picture may look dark in a room

The unit's internal temperature has increased. Remove any
objects blocking vent.
Is connection to other components correct? (See page 17.)
Is the correct input selected? (See page 25.)
Is picture adjustment correct? (See page 28.)
Is the volume too low? (See page 25.)
Have you pressed MUTE on the remote control unit?

This is not a malfunction. This happens when the cabinet
slightly expands and contracts according to change in
temperature. This does not affect the TV's performance.
