4.0 Precautions
1) If the power shuts down and stays OFF for a long period of time, an internal problem may have occurred (broken
part, etc.).
Turn OFF the main power switch on the plasma display then wait 1 to 2 minutes and try turning the power ON again.
If the power goes OFF again, the display requires service.
If the display operates normally, continue to use it.
2) When an image (still image, telop, etc.) is shown on the screen for a long period, there is a possibility that the
image could be burned in (not able to be removed). Manage this situation by making necessary changes in the
video software, projection method, system configuration, etc.
3) The following kinds of input signals could cause inferior image quality.
• Video signal that has been dubbed (copied) repeatedly
• Copyright-protected video signals
• Scrambled cable TV signals
• Signals with a sync signal and video signal that are extremely out of phase
4) The fan starts operating when the surrounding temperature is greater than 35 °C. The fan's rpm becomes faster as
the temperature increases; this is normal.
5) Screen-saver function (still image detection)
When an image having little to no motion such as a photograph or PC screen is displayed continuously, the brightness
slightly drops. To protect the plasma panel, the screen-saver function detects images with little to no motion then
automatically adjusts the brightness. This dimming is not an indication that the panel is failing.
Time until the screen-saver function operates:
• Normal-operation mode/menu mode: Approximate 3 minutes after the power is turned ON or after the input is
switched.
7 Self-diagnosis Function
When there is an connection or operation error, a message displays on the screen. After reading the contents of the
error message, refer to the chart below before checking the unit.
