6-3-7 Others
Problem Solution
The product is hot.
Since a PDP TV displays a picture on the screen by discharging plasma, operating for a long
time may introduce heat onto the panel. The internal heat of the panel is sent to the vent on the
upper part of the product, and users must take care not to touch the hot air from the vent.
The heat from the PDP TV does not indicate a defect or problem.

Problem Solution
There is no sound.
■
Increase the volume.
■
Press the Mute button.
■
There may be no sound when the internal amplifier setting is set to Off.
Set the Internal Amplifier Setting to On.
■
If you have connected the DVI signal to HDMI IN using the DVI
↔
HDMI converter cable,
you have to connect an additional audio (L/R) cable to the DVI Audio IN port to hear
audio.
The sound is very low.
■
Increase the volume.
■
Set the auto volume control to ON.
There is a lot of noise. Keep the antenna away from the power cord or connectors if possible.
The selected language does not

Press the Multiplex button to select the TV.
A "snapping" sound is emitted
from the product.
This sound may be heard when the product chassis shrinks or expands due to the surround-
ing humidity or temperature change.
This sound does not indicate a problem and there is no need to worry.
There is noise from the product.
A PDP TV may produce sound at a certain level when operating the fan to cool its internal
temperature. In addition, since the high-speed switching circuit and the high current may pro-
duce noise depending on the screen brightness change, a PDP TV produces more noise than
a conventional CRT TV.
