So, we had one of these at work. On its first trip out, someone dropped the thing and it kept flashing the lamp LED. Gave it to our IT guys and they said it's not worth picking up another bulb as they're very expensive and there's no guarantee the unit would work with a new bulb anyways. Basically, their suggestion was to trash it and buy another. This was months ago. I decided to take it home to mess with and just got to it this weekend. I check the bulb, doesn't look blown. I took the entire projector apart and reassembled it and behold, it works perfectly now! Not the greatest projector in the world, but for free, I'll take it!
