Problem: Nothing on projection screen
NOTE: If you accidentally use the
Main power switch to turn the
projector off while the lamp is on
or still cooling, allow the projector
to cool for 10 minutes before
attempting to turn it back on.
•
Make sure that the power cord is properly connected to a fully
functional AC electrical outlet. Make sure that the power cord
is also properly connected to the projector.
•
If the projector is plugged into a power strip, make sure the
power strip is turned on.
•
Make sure you have removed the lens cap on the projection
lens at the front of the projector.
•
Make sure the lamp is turned on. Press the
Power
button on the
keypad.
•
Check the projector’s lamp to ensure that it had not been in
use for over 2,000 hours and is securely connected in the lamp
module. See “Replacing the Projection Lamp” on page 31.
•
Make sure the lamp door and filter covers are correctly
installed.
•
Make sure you have allowed the projector to cool down before
turning it off. If the lamp has not cooled sufficiently, you can
not turn the projector back on immediately. Wait 10 minutes
for the projector to cool, then turn it on.

Make sure that the cables do not have any bent pins.

Make sure the image and audio have not been muted.
