Yes you need to reset the bulb hour counter.
It gives you a warning period of about 100 hours during which it will still turn on.
After that, it won't turn on and you have to do it blind.
The counter is in the processor, not in the projector itself.
I don't use my processor anymore since it broke. It has been nearly two years, but IIRC the one time I did reset the counter I did so by substituting a tv (actually a computer monitor) into the HDMI port that would normally run to the projector, but I left the rs-232 line connected to the projector. That let me see the menus so I could reset the counter. At least that's what I think happened...
FWIW, I bought 6 bulbs for about $600 total off ebay a year or two ago. They came from hong kong and they had slightly different part numbers than the original bulb and they might be be knock-offs, I don't know how to tell. But so far I've run through two of them and got roughly 3000 hours out of each with no complaints at all. I have not inspected all of them, but the three I've opened so far have been pristine, they even came with cheapo gloves in each lamp box to keep skin grease from getting on the bulbs during replacement.
