For those of you who have the Dell 1800mp DLP projectors and are having the issue of it either having erratic flashing LEDs and no power, or no power at all, here is the fix for them.
The power supply board in these projectors has one 3300uf 10v capacitor made by OST (aka really cheap crap). In fact, this is the only completely cheap knock off capacitor in the entire unit. This capacitor usually domes or bulges on the top causing the capacitance to drastically drop and therefore prevent the projector from powering on normally.
This capacitor must be replaced with a new high quality low ESR capacitor. I prefer nichicon capacitors as they are highly reliable and usually used in very high quality equipment. Once the capacitor is replaced with the new one, and the projector is fully reassembled, the projector should be ready to test. Please ensure your bulb and lamp cover are attached so the projector will power up.
Plug the projector in, and you should see the lamp and power LED flicker for a split second, after that the power LED should begin flashing blue on and off in 1 second intervals. Power up the projector, it should power up and ignite the lamp. Your projector should now be operating normally.
Enjoy!
