Red LED Behavior and Projector Errors

If the projector is not functioning properly and the LED is blinking red, con- sult Table 3 to determine a possible cause. There are two-second pauses between the blinking cycles.

	Table 3:
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 (see page 24) for
		repair if replacing the lamp does not solve
		the problem.
Four (4) blinks		The fan has failed. Contact Technical Sup-
		port (see page 24) for repair or replacing
		the fan.
Five (5) blinks		The projector is overheating. Check for a
		blocked air vent. Contact Technical Sup-
		port (see page 24) for repair if clearing
		the air vents does not solve the problem.
