Precautions - Pioneer PDP-425CMX Technical Manual

Precautions

6.1 Precautions
1) If the power shuts down and stays OFF for a long period of time, an internal problem has probably 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 is probable broken.
If the display operates normal, there is no problem in continuing to use it as it is.
2) When an image (still image, telop, etc.) is shown on the screen for a long period of there is a possibility that the
image could be burned in and not be able to be removed. This should be managed 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, and the fan rpm will become faster
as the temperature increases, however this is normal.
5) Screen-saver function (still image detection)
When an image having little motion such as a photograph or PC screen is displayed continuously, the brightness will
drop a little. This is because in order to protect the plasma panel, the screen-saver function detects images with little
motion ad automatically adjusts the brightness, and is not an indication that the display is broken.
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 error in the operation or connection, an error message is displayed on the screen.
After reading the contents of the error message, check the condition of the unit.
