Explanation
The lamp won't strike after five (5)
attempts. Check the lamp and lamp door
installations for loose connections.
The lamp counter hours have exceeded
lamp life hours. Replace the lamp and
reset the lamp hours counter.
The projector has shut down. Check to
see if the lamp door is open. If the lamp
door is closed, toggle off the projector
and wait one minute, then toggle the pro-
jector on again. If the lamp does not strike
after one minute, replace the lamp. Con-
tact your dealer (see page 30) for repair if
replacing the lamp does not solve the
problem.
The fan has failed. Contact your dealer
(see page 30) for repair or replacing the
fan.
The projector is overheating. Check for a
blocked air vent. Contact your dealer (see
page 30) for repair if clearing the air vents
does not solve the problem.
