36 Notes on Operation
I m p o rt a n t : Do Not leave stationary or letterboxed images on screen for
extended periods of time.
Displaying the same image frequently or for long periods of time can leave a subtle, but permanent ghost
image on the screen. Stationary black bars, like letterboxing, can also leave a ghost image if used too
frequently. To keep this from happening,
make sure you mix the types of images shown . It is best not to
have a stationary image displayed for more than 15% of the television’s total operating time in a given week.
Your projection television uses picture tubes to project images onto the screen. As they age, their light output
will gradually decrease. Under normal conditions, the tubes will age at a consistent rate across the screen.
Frequent display of stationary images though can cause the tubes to age unevenly. Uneven picture tube aging
is not covered by the warranty.
Some examples of signals which include stationary images include:
Letterbox top/bottom bars - These are the black bars at the top and bottom of the screen when a wide-screen
video is displayed on a standard TV.
Side bar images - These are the black bars on the sides of the picture displayed when a standard-size
television program is shown on a wide screen TV.
Stock-Market Report Bars - These are the “ticker” bars often displayed on the bottom of the screen during
financial reports.
Shopping Channel logos or pricing bars - These are the bright displays often shown on shopping channels
for extended periods of time.
Bright TV Station Logos - Subtle, low-contrast logos are less likely to cause uneven aging.
Video Game patters or scoreboards
On-line (Internet) web sites -
Web sites, or other computer-generated images that are not changed or are
displayed for extended periods of time.
Speakers
If you place speakers next to the television, make sure they are magnetically shielded. Because of their strong
magnets, ordinary speakers may cause distortion of the television picture if they are placed too close to the TV.
Cleaning
Normally, light dusting with a soft, non-scratching duster will keep your TV clean.
If you wish to wipe down the television, first unplug it. Then wipe gently with a soft cloth, slightly moistened with
water. You can add a few drops of mild liquid detergent to the water to help remove spots of oily dirt.
DO NOT allow liquid to enter the TV through the ventilation slots.
DO NOT use strong or abrasive cleaners on the TV.
DO NOT spray liquids or cleaners directly on the TV’s surface.
DO NOT rub or scrub the TV harshly. Wipe the set gently with a soft cloth.
