DP-3X THINGS YOUR SHOULD KNOW

(04) Fan Part # GS00822: In Digital Module

•
The below chassis utilizes a Digital Module which contains many sophisticated circuits. A cool-
ing fan is utilized in all Digital Modules (ATSC). It is normal for the customer to hear air circu-
lating and the fan running if the room is quiet. This can be compared to a computer cooling fan
as they are very similar. The customer may not be aware of the fact that his or her projection
television has a cooling fan incorporated. Please educate the customer with this information.
Do not assume that just because the customer can hear the fan that there is a problem with
the fan. Only if the fan produces a grinding or ticking sound should it be considered to be de-
fective.

(05) Did you know there is a Screen Saver in sets with a Photo Card Reader?

The following Note is in the Owner's Manual for Models with a Photo Reader:
•
NOTE: 1. Contrast will decrease automatically if stationary images such as digital still
photos are left on the screen for more than 3 minutes.
This screen saver will make the picture look dark and almost without color. If the customer isn't aware
of this feature and/or haven't read their Owner's Manual (Operators Guide), they may mistake this for a
problem.
A button must be pressed on the Remote Control to deactivate the Screen Saver. This Screen Saver
will remain in effect even if the pictures are changing. Example: During Slide Show.
Of course this is to prevent burning an image into the CRTs by a stationary image. This is normal op-
eration.
