Table 4: LED Behavior

Red LED Behavior	Explanation
One (1) blink	The lamp won't strike after five (5)
	attempts. Check the lamp and lamp door
	installations for loose connections.
Two (2) blinks	The lamp counter hours have exceeded
	lamp life hours. Replace the lamp and
	reset the lamp hours counter.
Three (3) blinks	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 Technical Support for repair if replac-
	ing the lamp does not solve the problem.

	port for repair or replacing the fan.

	blocked air vent (page 16). Contact Tech-
	nical Support for repair if clearing the
	vents/screens does not solve the problem.
