MAINTENANCE AND TROUBLESHOOTING
CARING FOR YOUR PROJECTION TV
Your projection TV will look better, have a longer life and per-
form better if you care for it properly.
First check to see that the TV is off. For added
safety, disconnect AC power to your TV.
NOTE: If you disconnect AC power to your TV
for an extended time period, you will have to reset
the clock.
Picture Screen Cleaning
Use a soft cloth moistened with warm water and rub lightly ill
the soiled areas of the screen. DO NOT USE A TISSUE OR
PAPER TOWEL, AS THESE MAY DAMAGE SURFACE.
Wipe only in the vertical (up/down) direction (along the
grooves). If there is a dirt buildup, a mild solution of warm
water and Ivory dishwashing detergent may be used. Use dry
soft cloth to dry the screen. Care should be taken to avoid
scratches or damage to the screen surface.
NOTE -- The TV screen is easily damaged. Avoid acciden-
tal contact with the screen.
EXTENDED ABSENCE
Before an extended absence (such as a vacation) you may
want to disconnect AC power to your TV. This will protect
the projection TV from possible damage from lightning or
power line surges. If you have an outdoor antenna, you may
also want to disconnect the antenna from the wall plate con-
nection center
NOTE: If you disconnect AC power to your TV for an ex-
tended time period, you will have to reset the clock.
PICTURE INTERFERENCE
Your picture may be affected by interference caused by one or
a number of factors. These include:
Nearby Automobile Ignition, Electrical Appliances, etc.
Which causes a speckled, streaked picture. This is most notice-
able in weak signal areas.
Snow in Picture Caused by insufficient signal. Usually
caused by the TV being located too far from the TV station or
by an improper antenna installation.
Ghosts or Reflections Caused by signals being retlected
from surrounding buildings, water tanks, or other high struc-
tures.
Radio Signal Police, amateur or CB radio transmitters may
cause interference.
These interference problems can often be corrected through
the use of a better antenna, signal amplifiers, or various filter
devices. See your TV dealer for additional information, and ac-
cessories available for your projection TV.
