I have a dell 2300mp projector. I replaced the lamp with a brand new
one. I plug the power cord and the green light on the power button
comes on flashing. I press the power button and the light turns solid
green but the lamp does not turn on and the fan does not turn on. After
4 to 5 minutes the lamp warning light comes on. I changed the fan and it did not solve the problem. Please give me some ideas. Thank You

Looks like there is power supply problem as well as the lamp.
1 Clean all filters 2 Check out power supply (usually a few capasitors need to be replaced) 3 Wuld be a good idea to check the lamp in wokring projector, but if the "Lamp" light is constantly on it is more likely a faulty lamp as well.
If the fan is not working, the lamp will not fire. If you have the owner's manual, it should indicate what the flashing lights mean. Check to make sure that the panels are seated properly. When you replaced the lamp, the outer cover was removed. If that is not seated back 100%, the unit will not work. There are a number of safety "checks" built into the unit to prevent damage and possibly fire as the lamps get really hot.
Check the items above and let us know your progress.
I was told by an expert that the fan should come on as soon as heat starts to come on. You should never turn a projector off with out the fan running for a while to cool the bulb down. Each projector is different but the fan has to operate on then all. There is so much heat in the bulbs that air has to keep them cool when they are operating as well have to cool gradually when they are shut down.
The fuse is a short round maroon colored part to the left of the power plug looking at the power supply module from the direction that you would connect the cord to. it is labeled F1 and it is a 4a 250v. This is not the problem with my power supply though. I suspect one of the components under the heatsink is bad. as you all know don't bother calling dell.
Have the same problem here. Have two of these units. Took the bulb out of the one that had the Lamp light on, and put it in the other projector. The other projector worked perfectly. I have three bulbs, they all work in the one projector, they all cause Lamp Light in the other one. The manual states nothing about hard resetting the unit. Also note that, the fans do not power up instantly on power on, they come on about 5 seconds after pressing the power button.
