After some experimenting I have come up with an alternate power supply for the Dell 2300MP Projectors. At first I bought some that did not work then I found out that with a slight modification this CT-300 power supply works.
This is my collection of dead Dell power supplies.
This is a size comparison. The new power supply is a little bigger but the projector has plenty of room for the power supply. Note that the cable to the motherboard is backwards and that there are 2 extra pins towards the 110 volt connector end of the power supply.
The new power supply will not turn the projectors bulb on. It needs a modification to supply 5 volts to the extra pin that is not ground via a 1 K resistor as seen in this picture.
