Hi Carl,

It sounds like you may have an issue with either the bulb or power supply. In either case, you will need the help of a professional service center. Feel free to send me an e-mail at and I can have one of our techs contact you. Home

Dear Sirs, I have a BENQ PE8700 projector. I know it's outdated, but it still suits me fine. I've already changed the lamp, and this new one is 1000 hours old. I am recently having a problem:...

If the bulb on this projector is filament less then it may be a bad ballast. If it is that kind of a bulb the ballast is like the starter on a florescent bulb that excites the internal gases for light to be emitted. If it conks out, the bulb stops emitting light even though the cooling fan stays on.

BenQ DX 650 Won't power up making clicking noise

Those units are designed to be fan cooled after the bulb shuts off. When the cord was pulled, the unit lost power and without the fan, sat there and cooked. Could be a thermal fuse, could be the bulb.

Lamp died and remote does not work

I don't think the problems are related. The bulb shouldn't have failed as it is rated at 2000 hours. As for testing the ballast I don't believe that a conventional meter would do it. You would need a lamp testing device. For more go to Since projector lamps or ballasts are not cheap you may want to have a a/v repair shop check your projector, because of the early bulb failure.

Ballast error status - lamp voltage too high

You need to replace the balast as the voltages are buringing the bulb out and this is caused by a balast that is bad. The baslast is what the bulb connects to this has a sensor on it that relays voltages and heat back to the main control unit.
