With some stabilization help from my wife (standing on a sofa while trying to mount a projector is precarious at best) we got it up and running. So far, so good. It's been on a couple hours with no temp light coming on.

No words of wisdom? I'd really hate to have to buy another projector if I can salvage this one at all.

OK, here's what's wierd. Before the repair the projector would make grinding noises on startup and occasionally while watching. Pretty sure this was symptomatic of the iris lubrication issue. I've used 3in1 on a Q-tip several times to combat this issue, usually successfully for a while. Since the power supply repair it has been very quiet. The fans fire up on start up but are as quiet as new, AFAIK. Almost like a new lease on life. Time will tell. I doubt that I will spend this much on another repair. It's been stalwart if not too bright.
