Possible Solution
The lamp driver has overheated. The display
automatically shuts down. Turn the display on
again after the projector cools down. If the
problem persists, contact Dell.
A projector fan has failed and the projector
will automatically shut down. If the problem
persists, contact Dell.
Try to press the Menu button on the panel for
10 seconds to unlock the OSD. Check the
Menu Lock on page 29.
The battery may be low. Check if the laser
beam transmitted from the remote is too dim.
If so, replace with 2 new AAA batteries.
