OK so I have a BenQ DX 650 I've had for a few years and the other day we where watching a movie and someone accidentally tripped over the power cord and shut the projector off well I went to plug it back in and it made a clicking noise and the fans and temp light started flashing well obviously it was hot, so after it cooled down and I went to turn it back on it mad the same clicking noise it would start for a sec and stop for another and then the lamp light would blink and the fans would just run. So I tried to power it up again and maybe out of about 6 to 10 tries the eventually it would work.. Once the lamp was on it wouldn't shut off and it would work fine.. Well I had to do this every time I use it.. My final question is if the lamp or ballast is bad it wouldn't power up at all. I have opened it up and the clicking noise is coming from the surge arrestor on the ballast, its sparking up emitting a blue light making the noise..

Hi,
The problem comes in the Lamp unit generally. check the condition of Lamp.

Hi,
Check if the unit has a Filter Timer ? If it does have one - check the hours on it and reset it.
If the problem still occurs or there is no filter timer in the Menu - check that all your fans are running.
Hope this is of help
Goodluck,

this model is prone to over heat. look near the lamp for the temp sensor it is most likely bad
SOURCE: 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.

I have the same problem, however, my lamp wasn't replaced. Projector working great, just started today. Filter cleaned, reset lamp time, neither helped. Any luck yet?
