If you follow the next few pages after that post you'll see my tribulations.
On my second bulb now, around 700 hours or so. So far so good, but I'm starting to get nervous again. The worst part is, at around $200, I'm okay having to replace the bulb every 1,000 hours or so, but I just wish the damn thing wouldn't just shut down out of nowhere when it decides the bulb isn't "worthy" anymore.
For what it's worth I did try to search the forum... but my wording must have been... rubbish. :P
It certainly seems like it's the exact same problem though. I just figured since the brightness hasn't really gone down, and the fact the projector can turn on for a few minutes meant it wasn't really bulb related. As frustrating as it's been for me, it must have been 100 x worse for you (and the couple other I saw effected) learning what the resolution was.
Glad to hear your new bulb seems to be working out - fingers crossed there was just a bad batch of bulbs.
Edit - I removed the bulb, cleaned the surface, and then reinstalled it. Figured there's no harm in it. I've tested it now for 2.5 hours (all at once) and it remained on.... Now, hardly conclusive I know, but I'm sort of limited in terms of "tinkering time" due to family obligations at the moment. Either way, I thought I'd at least put my experience up in case I actually get some more life out of this bulb (will be ordering another regardless, as I certainly don't have much faith in this one).
Edit 2 - Another 2.5 hours on it today without it shutting down. Knoking on wood at this point.Edited by jcdennis - 12/23/12 at 2:26pm
