Just wanted to update on this. I have not been able to trace back where the missing crystal goes (it goes to a lead that runs to the other side of the board and there is a part over that area so I cannot see where it comes from after that)
BUT! We are not out of luck yet. I happen to be getting another one of these in (working, and 100% identical this time ) so I should be able to pull the board out and identify the parts. The projector will be here late next week/early the week after, so I will let you know around then what I have found

It is good you have another similar unit coming to id all those parts.
Just for future reference, if you did not have another unit coming, you could set your DMM to continuity with beep, put 1 probe on a crystal pad and use the other probe to drag across the pins of various multi leg ic's until you found a beep. Then also verify other pad to same ic on adjacent or 2 pins.
The working one came in yesterday, and I opened it today and removed the mainboard. The missing crystal I need is 27.0000MHz, and the missing surface mount resistor is 110K ohms. I've ordered the 2 parts (got a 10 pack of crystals, was only $4) so now I just wait until they arrive. Hopefully these 2 missing pieces are all that's keeping it from working.
At the very least, nothing will be broke off anymore
Also, thats a good suggestion MT, (which I could have tried of course). I'll keep that in mind the next time I have a similar issue to this. I can't expect to find doubles of everything all the time
Okay MT, finally got some time to do this tonight. I put the new crystal on the mainboard, as well as the new resistor (some crafty and wicked looking solder work I might add, and by wicked I mean I was lucky to get the damaged foils to solder back to the crystal), and the projector is now functioning 100% perfectly!! See pic below showing it running!
Thanks for your help MT, though I know you didn't have to participate too much on this one, but someone to bounce ideas off of always helps!
