I'm still waiting for Optoma's response. My contact person has been away on vacation so I'll speak to him tomorrow, with any luck.
I don't know what to do just yet.
I don't mean to scare people away from this unit because if you get a proper one, the image is truly stunning. It's exceptionally bright, contrasty, liquid (very film-like) and sharp as a tack. But the problems I've had are crippling and does not inspire any confidence in their manufacturing or QC. It's not just the 6800. Mystery was telling me about his H31/H57 experiences and he has pretty much gone through as much aggravation as I have with those machines. I'll let him tell you about that if he wants, but my situation does not appear to be completely isolated.
It's a shame really. With proper QC, this is one killer package.
Small world, indeed. I wouldn't worry too much about it. Basically, I would check three major things with this package:
-- Screen. Make sure the screen actually says Gray Wolf II on the casing. If you scroll back a few pages I posted pictures of what it should look like. If you can't find them, just PM me. There have been forum members (more than one) that have gotten incorrect or old repackaged screens from Optoma, even when the boxes indicates the right one.
-- Also, make sure there are no obvious dents, rust or signs of mistreatment. When you pull the screen down for the first time, there should be a protective film to protect the felt lining at the top.
-- As for the projector itself, just do a quick calibration, pop in a movie and watch it. If you have smudges or dust blobs, it will be obvious as soon as you get a black dark screen. If your color wheel is excessively noisy, you will notice almost right away. If nothing is obviously wrong, don't fret about it.
You can also check that the image is uniformly sharp all round. In one of the menu options, you can toggle the location of the OSD between about 6 different screen positions and you can use the menu text (which are very sharp) to gauge uniform sharpness. Both of mine were perfect -- single chip DLPs tend to excel in sharpness.
Have fun with your new toys, guys.
