08 Cautions and Warnings In rare cases, some pixels can be permanently switched off, or on, resulting in either a black or colored pixel permanently fixed on the screen. This effect is common to all plasma displays because it is a consequence of the technology. 8.7 Prevent Burning After-Image Lag If an image with very high peak luminance or fixed images such as time of day indicator or channel logs are displayed for more than a minute, after-image lagging may occur due to the remaining electric load. After-Image Lag refers to a ghost of the still image remaining visible after the picture is no longer being shown. This is not a malfunction. The ghost-image remaining on the screen disappears when moving images are shown in full screen. Image Retention (a.k.a. Burn-In) If the same image is displayed continuously, or for shorter periods over several days, a permanent after-image may remain on the screen. This after-image is permanent because the fluorescent materials burned. Burned images may fade eventually after playing other video sequences but do not disappear completely. Burn-in tends to occur more easily soon after the product is purchased. Display Samples Susceptible to Burning • If 4:3 aspect ratio images are displayed in their original size repeatedly, the screen other than black or gray bars on the left and right, is susceptible to burning. • If 14:9 or 16:9 letterbox images are displayed in their original size repeatedly, the screen other than black or gray bars at the top and bottom, is susceptible to burning. • If fixed images such as time of day indicator or channel logos for an extended period or repeatedly, the images are susceptible to burning. • If static images, such as a fixed image from a PC or a TV game unit, are displayed for longer periods, the images are susceptible to burning. Avoid Image Retention To avoid image retention as much as possible, refer to the guidelines below. • Avoid displaying images susceptible to burning whenever possible. • Display content in a wide aspect ratio (no black or gray bars on any side of the content). Use the SCREEN SIZE button on the remote control to set your flat panel display to a wide-viewing screen mode (WIDE, for example). Refer to "5.2.1 Choose a Screen Size (Automatically or Manually)." • Select auto screen sizing (page 37) then set the Side Mask detection function to Mode 1 or Mode 2 (page 40). • Set the Brightness Sync. option to Auto (adjusts the side mask brightness according to the brightness of screen images) when the screen size is 4:3 and Side Mask detection is set to Mode 1 or Mode 2. Refer to " Lighten Side Masks" on page 41. Setting the Energy Save function to Save 1 can further improve the effect (see page 33). • Leave turning On the Image Orbiter (see page 33). Long Life Settings The Long Life Settings option simultaneously optimizes the related settings to guard against image retention. For details, see "4.2.1 Extend Your Panel Life." Image Orbiter Another built-in feature to protect against burn-in is the Orbiter function. Orbiter automatically changes the position of the picture imperceptibly while the image is on screen. For more information about the feature, refer to "4.2.4 Turn On the Image Orbiter." 86 En
