Just to address a couple questions...

If you're talking the "120Hz", "240Hz", the answer is a qualified "yes". First it's probably important to realize that your DLP operates at a native refresh rate that is much higher than any "xxxHz" display of any other technology. In reality, what "120Hz" means on a TV, is that it includes Frame Interpolation, it's digital processing that will interpolate new frames between source frames, so it will effectively convert 24fps content (movies) to 120, or 240Hz. This has the effect of reducing blur, but it also fundamentally changes the look of motion, ie it creates the "Soap Opera Effect".
Now most modern projectors have various settings that trade blur reduction for less effect on motion, I can't really speak to that, a lot of folks like Frame Interpolation set to low to clear up blur without doing too much damage. But I think it's really no substitute for native motion handling like DLPs have.
Many are rated at 1700 -2400 lumens, isn't that comparable to the HT5000?
Seegs and Mike already said it indirectly, but there are no "home theater" grade projectors* that put out over 1000 Lumens for under $10k other than the Sony VW350, and the Epson LS10000. Everything else that claims ridiculous brightness can only do that in uncalibrated, non-useful modes.
*There are a number of DLPs that can pump out over 1000 Lumens, and they are "Home Theater" machines but they're not remotely in the same league as your HT5000. DLP technology has been "stable" (some would say stagnant) for the past 5 plus years. My Planar 8150 is a seven year old design, and it's still a top class machine, at least within DLP space, only bested by machines like your HT5000.
I think I may have to bite the bullet and get it fixed. No matter what I do. Unless someone else would want to buy it and get it fixed. Wishful thinking I suppose.
One way to look at it, $3k is a bargain for a working HT5000, you can't buy anything new with near the performance of that for anywhere near that price.
