Acer H6520BD - lamp won't turn on, everything else seems ok

nal

Hi, I own a  Acer_H6520BD projector. When I tried to turn it on, everything looked ok but the lamp. Both the temperature and lamp LEDs were off, the power button LED was blue and I could hear the fans. Only the lamp wouldn't turn on.

 

According to the LED Messages troubleshooting guide, everything should be ok and the lamp shouldn't be broken.

 

Any ideas on what could be wrong and how to fix it?

 

Thanks in advance
