Explanation

 

 

One (1) blink

 

The lamp won’t strike after five attempts. Check the

 

 

 

lamp and lamp door installations for loose connectors.

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 the lamp. Turn the

 

 

 

projector off and wait one minute, then turn the

 

 

 

on. If the lamp does not turn on, replace the lamp.

 

 

 

Contact Technical Support for repair if replacing the

 

 

 

lamp does not solve the problem.

 

Four (4) blinks

 

A fan has failed. Contact Technical Support for repair.

Five (5) blinks

 

The projector is overheating. Check for a blocked air

 

 

 

vent. Contact Technical Support for repair if clearing

 

 

 

The air vent does not solve the problem.
