Pioneer PRO-950HD Fan motor noise, To use this product for a long period of time, Image Retention

Important User Guidance Information 01

Fan motor noise

The rotation speed of the cooling fan motor increases when the ambient temperature of the plasma display becomes high. You may hear the sound of the fan motor at that time.

To use this product for a long period of time

•Energy Save maintains efficiency of the screen for a long period of time by decreasing picture brightness and lowering power consumption. Setting Energy Save to “Mode 1” is recommended for increased efficiency.

About the menu window size following video format switch

The video program that you watch may be high definition (HD) or standard definition (SD). This plasma display is designed to scale to each type of definition properly. If the video program’s definition type changes while a menu window is displayed on the screen (for example: HD → SD or SD → HD), the menu size may temporarily shrink or enlarge until the scaling is completed. This may happen, for example, when you switch between television and an external digital video recorder

(D-VHS), or when your recorded program switches between different definition types, while the on-screen menu is being shown.

If this happens, the menu will return to its normal size after two to three seconds. This action is normal, and does not indicate a problem with your plasma display.

Image Retention

When a static image is left frozen on a display for several hours, a faint imprint of the image, known as image retention, can remain. This image retention may be temporary or permanent. Although caused by different things, image retention can occur on all display technologies, including plasma and LCD. On today’s plasma displays, permanent image retention is less of a worry. Most image retention can be improved simply by watching moving video.

Image retention, also known as burn-in, can occur in all phosphor-based display systems (including CRT television systems–both direct view and projection–as well as plasma displays). Displaying the same still images for long periods should be avoided as permanent image retention or burn-in may occur. Recommended guidelines are as follows:

Do not display static images for long periods (such as still images, fixed images from PC or TV game equipment, and/or fixed images such as time of day indicator or channel logo display).

Do not display content in the 4:3 aspect ratio (black or gray bars on left and right side of content) or letter-box content (black bars above and below content) for extended periods of time, or use either of these viewing modes repeatedly within a short period of time. This plasma display is equipped with multiple wide-screen viewing modes; use one of these screen modes to fill the entire screen with content.

Displaying dark images after displaying still images for a period of time may cause image retention. In most cases, the image retention can be corrected by displaying bright images for a similar period of time.

If you display still images on your plasma display for long periods of time, image retention may be irreparable.

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.

1After-image lagging due to remaining electric load

When image patterns with very high peak luminance are displayed more than one 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.

2After-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.

Note

•When a program menu, TV Guide screen or frozen image is displayed for 5 to 10 minutes, the system automatically turns the image off to prevent damage from screen burning.

•To minimize image retention, the display position is automatically changed imperceptibly when watching plasma display.

Some parts of the picture may not be visible (see Orbiter on page 64).

Minimizing damage from screen burning

•Set the Side Mask detection function to “On”. The High Definition 16:9 aspect ratio images containing side masks will be detected automatically and side masks will be added or the image displayed in full screen.

•We recommend that you enjoy watching images displayed in full screen, except when doing so may result in copyright infringement. The use of images displayed in screen sizes different from the original video for financial gain or in broadcasting for public viewing may result in infringement of the legally enforceable rights of the copyright holder (see page 62).
