Red LED Behavior and Projector Errors
If the projector is not functioning properly and the LED is blinking red, consult 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 shutdown. 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 projector on again. If the lamp
does not strike after one minute, replace the lamp. Contact Technical Support (see page 18 )
for repair if replacing the lamp does not solve the problem.
Four (4) blinks
The fan has failed. Contact Technical Support (see page 25 ) for repair or replacing the fan.
Five (5) blinks
The projector is overheating. Check for a blocked air vent. Contact Technical Support (see page
25) for repair if clearing the air vents does not solve this problem.
