Hi I have Benq mp612c projector, i used for a little period only.But now my projector is not turning on and indicates all three orange lights glow when i switch on power. But the projector is not starting and no beep sound which normally we heard while switch on. And also I never set any pass word protection. I am unable to understand the problem... If anybody advice me to fix the problem...Thanks...

Check the ballast board. It is the one that has the wires going directly to the bulb socket.

You should see the user manual. Maybe you can find the solution there.

This happens during the bulb initialize phase. Your bulb is bad and will need replaced.

Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

Possibly a faulty ballast unit not able to fire the lamp.

Hello
If the Lamp light and power lights are blinking orange, the lamp driver has failed, and the projector will automatically shut down. Unplug the power cord from AC mains wall socket, wait for three minutes and replug and see whether it helos you. If not, contact Dell service center.
OK.

Hi you should check the power cables and switches for the projector

hi icant solve this problem but i am looking for the same thing. for my benq mp612c. did you have any luck?

you can go to the BenQ website and download a manual for your particular projector. It should tell you what the lights indicate.
