Possible Solution (continued)
If the LAMP light is blinking amber, the
lamp module connection may be
disrupted. Please check the lamp module
and ensure that it is properly installed.
If the LAMP lights and the Power light is
blinking amber, the lamp driver has failed
and the projector will automatically shut
down.
If the LAMP and TEMP lights are blinking
amber and the Power light is solid blue,
the color wheel has failed and the
projector will automatically shut down.
To clear the protection mode, press and
hold the POWER button for 10 seconds.
The projector has overheated. The display
automatically shuts down. Turn the
display on again after the projector cools
down. If the problem persists, contact
Dell.
If the projector fan fails, the projector will
automatically shut down. Try to clear the
projector mode by pressing and holding
the Power button for 10 seconds. Please
wait for about 5 minutes and try to power
up again. If the problem persists, contact
Dell.
The battery may be low. If so, replace with
two new AAA batteries.
