Iâ€™ve had some trouble with my PJ and bulb time. Spent a lot of money ($1500) on premature bulb blow-outs, explosions etc. The last time I sent my unit in has equated to the best bulb time Iâ€™ve ever had. So, here is what I have learned, on my own and by Sanyo techs to get the best bulb time.
Regardless of what the manual says, check your filter every two weeks. If it is dirty, clean it out. If you get way less time than you think you should get, have the company check the fan speed on the PJ.
If you "soft" power your PJ off, and there is still power going to itâ€¦.turn off the entire power.
Vacuum any openings on your PJ with a vacuum. Any open air holes should be vacuumed once a month.
Best advice I can give from experience. Since Sanyo will not publish bulb times, it is really hard to get a grip on what you should get.
I am now on a bulb almost at 1000 hours. And it is still very bright.
Before, I got, 350 on a bulb....450 on another bulb....550 on another bulb.
