This thread really doesn't need another post, and enough has been said about what I think is not just a random problem
with the HD 72/6800, but what appears to be a case of engineered obsolescence. I recall Apple had toyed with the idea of a two year life-span for electronics (either by means of keyed software or hardware failure tolerances). It appears Optoma has implemented this strategy, or am I just imagining that most of the failures are happening in roughly the same time-frame as determined by lamp-hours?
That having been said, I've contacted Optoma; same song and dance as most of you have experience, and I have no intention of having them inform me that there is a bulb issue for a price-tag of some 500+ dollars. So,I took the machine apart, cleaned the inside, removed and reinstalled the bulb . . . and had the bulb stay on for a full 30 seconds longer than usual for my trouble. Strange that this should have made any difference.
In any event, I do have a question: what is the shortest time a replacement bulb has lasted after the replacement of the initial bulb? More to the point, would it be worth the $360.00 CDN investment in a new bulb? That's six times less than an Epson 1080UB, but I don't want to have six times the trouble either. So, would anyone hazard giving advice as to whether even that amount of money is worth putting into this machine?
Finally, if this were a baby bottle issue we'd probably find more sympathy for our plight with this projector. I suspect even consumer protection advocates would not come to the aid of something that really is a luxury and an indulgence (an oblique reference to certain events of October 31, 1517)
Anyway, just a brief note as to whether the current crop of bulbs might be more stable would be helpful.
