I have 2 of these Dell 1800mp projectors here. Both had domed capacitors on the power supply boards. Repairing those made them fully power up like they should. The problem with both of them now is, the lamps will only ignite for a few seconds, then go back out. Sometimes they wont ignite, and on one, it will sometimes ignite and stay working perfect.
Would this be capacitor related as well even though the capacitor on the ballast appeared to be fine?
For the record I tried them with 3 different bulbs, which I know one works because one of these projectors stayed working for a few hours last night after repairing the PSU. So im not inclined to believe its bulbs, but I am not 100% sure either.

So out of 3 lamps, 1 will work in 1 machine. So is it safe to say then that the other 2 are definitely bad? If yes, then that leaves 1 lamp that is maybe ok. Here's is the problem. The ballast monitors the amount of current a lamp is using and when that current hits a certain point the lamp is determined to need replacement. And 1 ballast can be slightly different from another. So it is hard to make any suggestions without knowing the true condition of any of your lamps. Your flashing lamp led is saying it needs a lamp so at this point who knows.
I think I'm going to agree with you on the lamps. I say this because I just repaired another dell projector that had a damaged color wheel, and I know it works fine other than that. I put one of these bulbs in and it did the same exact thing. I'll go ahead and purchase a couple new lamps and see how it goes from there. These were used ones that came in the projectors so I knew there wasn't any guarantees.
I think last night I just got lucky with the one bulb working for a couple hours after I repaired the PSU in the projector. For what its worth the projector said the lamp was used for 1025 hours, which is about 1/3rd its expected life. The bulbs look genuine but I have never seen an actual dell bulb so I can't say that for sure.
I was going to post the same issue on a Mitsubishi projector that I also used one of these bulbs in and it did the same exact thing, so since its the same issue across different brands and models of projectors I am leaning toward it being bulbs too.
