Hitachi CMP5000WXJ STANDBY/ON indicator, Panel sticking and after-imagelag, Additional cautions

Additional Information

Although this unit incorporates high precision technology in its design, please understand that there may be extremely slight pixel breakup, or light emission fault.

Note

In order to protect the panel and internal circuitry, this display is provided with a cooling fan designed to turn on/off and change speed automatically in accordance with ambient temperature conditions (the fan sound will change in accordance with its speed).

Additional cautions

•If the power is automatically turned off during operation of this unit, the following reasons may be the cause.

1 Is the POWER MANAGEMENT or AUTO POWER OFF function set to ON? (page 20).

2Is ambient temperature too high?

3The internal temperature has risen abnormally due to blocked cooling vents, overheating of internal

electronic parts, or other factors.

4If the display is moved suddenly from a chilled location to a warm room, or if the room temperature rises suddenly, condensation may form on internal parts. To protect internal circuitry, the display is

provided with a condensation detector that automatically disables power in event of internal condensation; in this case, allow the unit to dry thoroughly before using.

If the power is automatically turned off for a reason other than the above reasons, there could be a malfunction. In this case, unplug the power cord from the power outlet and request repair from your nearest sales outlet.

•The plasma display panel of this unit is very bright and viewing it a close distance will cause eye strain.

We recommend that you view the screen from a suitable distance (9.8 to 19.7 feet (3 to 6m)).

STANDBY/ON indicator

During operation of the Power Management function, the indicator will flash green at intervals of about 2 seconds (page 20). If the green light displays a flashing pattern other than the above, an error message is indicated. Consult any onscreen messages (page 27) and check ambient conditions (temperature, condensation, etc.) and respond accordingly (page 28-29).

If the problem persists, disconnect the power plug and consult your dealer or a service center.

When STANDBY/ON is pressed to set the unit to the standby mode, the indicator will flash red for several seconds (page 16). Other than this, if the power turns off by itself, or refuses to turn on, or if the red indicator conditions flashing, a malfunction may be indicated. Immediately disconnect the power plug and consult your dealer or a service center.

About the plasma panel’s protection function

The brightness of this display will deteriorate slightly when an image with little movement such as a photograph or computer image is continuously displayed. This is caused by the plasma panel’s protection function which detects images with slight movement and automatically adjusts brightness to protect the display, and is not a malfunction.

The screen-saver function begins operating when the display detects no or little screen movement for a period of about three minutes.

CAUTION

Panel sticking and after-image lag

•Displaying the same images such as still images for a long time may cause after-image lagging.

This may occur in the following two cases.

1.After-image lagging due to remaining electrical load When image patterns with very high peak luminance are displayed for more than 1 minute, after-image lagging may occur due to the remaining electric load. The after-images remaining on the screen will disappear when moving images are displayed. The time for the after-images to disappear depends on the luminance of the still images and the time they had been displayed.

2.After-image (lag image) due to burning

Avoid displaying the same image on the Plasma Display continuously over a long period of time. If the same image is displayed continuously for several hours, or for shorter periods of time over several days, a permanent after-image may remain on the screen due to burning of the fluorescent materials. Such images may become less noticeable if

moving images are later displayed, but they will not disappear completely.

•The power control function can be set to help prevent damage from screen burning (page 25).

Note

Special precautions must be employed when using the plasma display as a surveillance monitor or in other applications where a fixed image will be displayed for extended periods of time. Before using the monitor in such applications, consult your dealer for advice.
