BEFORE REQUESTING REPAIR
If you think a malfunction may have occurred, check the following items.
When this happens Check
• The power does not come on. • Is the power cord disconnected?
• The picture does not appear. • Is a cable to other equipment disconnected?
• The remote controller does not work. • Are the batteries installed with their poles reversed?
• Are the batteries flat?
• Are you operating from far away?
• Are you trying to operate with the transmitting section of the
remote controller not facing the reception section of the
display?
• Is there any obstruction between the display and the remote
controller?
• There is a creaking sound. • This sound is generated by the expansion and contraction of
the cabinet owing to change in the room temperature.
• There is a humming sound. • The Plasmavision has heat radiation fins to prevent its internal
temperature from rising too high during operation. The sound
you hear is the fan rotating.
• There are dots on the screen. • Is the connected tuner being affected by interference from a
car, train, high-voltage line, neon light, or the like?
• The colors and tints are not good. • Do any of the video settings need readjusting?
• There is no sound. • Are the internal speakers switched off?
• ERROR MESSAGE CONDITION 1 is displayed. • The fan is malfunctioning. Switch off the power.
• ERROR MESSAGE CONDITION 2 is displayed. • The temperature inside the set has risen far too high.
Switch off the power. (The power can be turned on once the
temperature lowers.)
BEFORE CLEANING
Always unplug the power cord from the
socket.
Cleaning the cabinet and remote controller
Do not use benzene, paint thinner, or other solvents. They
can cause deterioration or paint peeling on the cabinet,
the screen front filter, or the remote controller.
Wipe gently with a soft cloth.
CARE AND MAINTENANCE
For stubborn grime, soak the soft cloth in neutral cleaning
agent diluted with water, wring it out well, and wipe clean.
Then, finish with a dry, soft cloth.
Cleaning the screen
Wipe gently with a soft cloth.
The surface of the screen is easily scratched, so do not
strike it or rub it with anything hard.
