Table B-3. Red LED behavior and projector errors
Red LED behavior Explanation
One blink The lamp will not strike after five attempts. Check
the lamp and lamp door installations for loose
connections.
Two blinks The lamp counter hours have exceeded lamp life
hours. Replace the lamp and reset the lamp hours
counter.
Three 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 projector on again. If the lamp does not strike
after one minute, replace the lamp. Contact IBM
technical support for repair, if replacing the lamp
does not solve the problem.
Four blinks The fan has failed. Contact IBM technical support for
repair or replacing the fan.
Five blinks The projector is overheating. Check for a blocked air
vent. Contact IBM technical support for repair if
clearing the air vents does not solve the problem.
