after-image to remain on the Projection TV screen.
Examples of still pictures include logos, video games, computer images, teletext and images displayed in
16:9 mode.
Note:
The permanent after-image on the Projection TV screen resulting from fixed image use is not an

Checks
The unit contains many plastic
parts. For this reason DO NOT
use benzine, thinner or other
chemicals to clean the unit.
DO NOT bring into contact with
insecticide or other volatile
substances.
DO NOT allow the unit to come
into contact for extended periods
with rubber or vinyl products. Remove dirt and soiling by wiping with a light cloth.
Even if the unit is heavily soiled, do not apply cleaner directly
to the unit. Soak a cloth in a solution of neutral cleanser
thinned with water. Then wring out the cloth, wipe the unit
clean, and finish by wiping with a dry cloth.
Do not use any type of cleansers on the picture screen.
Dust will accumulate on the picture screen. Please wipe
with a soft cloth from time to time. If you use a
chemically treated cloth, please be careful to follow the
instructions that come with the cloth.
Before you call for service, determine the symptoms and make a few simple checks as shown below.
