Precautions

6.1 Precautions

1)If the power shuts down and stays OFF for an extended time, an internal problem has probably occurred (failing part, etc.).

Turn OFF the main power switch on the Plasma Display then wait one to two minutes then try turning the power ON again.

If the power goes OFF again, the display needs to be serviced.

If the display operates normally, the power reset has cleared the issue.

2)When an image (still image, telop or subtitle, etc.) is shown on the screen for a long period, there is a possibility that the image could burn in. This should be managed by making changes in the imaging software, display method, system configuration etc.

3)The following kinds of input signals could cause inferior image quality (when a PDA-5003/PDA-5004 card is installed).

•Video signal that has been dubbed (copied) repeatedly

•Copyright-protected 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 32 °C (the fan rpm becomes faster as the temperature increases, 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 image may appear dimmer. To protect the plasma panel, the screen-saver function detects images with little or no motion and automatically adjusts the brightness. This action is not an indication that the display is failing.

Time until the screen-saver function operates:

•Normal-operation mode/menu mode: Approximate three minutes after the power is turned ON or after the input is switched

7Self-diagnosis Function
