One good thing is that you are running XP. Will work on the premise (that you have posted) worked before and the driver (ForceWare91.31) was the only thing changed.
Let's try the easy ones first. Activate twin/dual view in your Display Properties. Right click on any clear area of your desktop, click on Properties, click on Settings tab, select monitor 1 or 2 depending which is your primary and which is your projector. Check (or uncheck-whichever works) on box "Extend....". Apply, OK.
do the same with nView Properties.
The hard ones are registry and/or inf editing, though I am reluctant to even suggest.
Incidentally, there is an application that is supposed to facilitate twin or dual view configuration, UltraMon. This may be better/safer way to address your concern.
If all else fails, you may have to rollback/downgrade your driver.

You have a blown bulb. I have the same projector and it had the same problem. The bulb is blown replace it and you should be fine.
If you are not sure of my solution you need to know that your projector will look like it is starting up and the bulb will partially light up but never come up to full brightness, then the projector will shut down. This will happen over and over until it just gets to the point it just turns on (the fan comes on and then about 30 - 60 seconds later the fan turns off.
Replace the bulb and you should be fine.
Been there done that!

Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.
I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

SOURCE: optoma ep739 won't power up
The lamp cover has a disconnect that won't allow power while the cover is off. Sometimes the piece of metal gets bent out of place.
Try removing the cover for the lamp, and bending the little piece of metal forward.
It worked for me!!!!

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?
Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.
