I haven’t had a pleasant experience with my BenQ W7000. It was DOA in early September 2012. Returned to BenQ (Sydney) and was supposedly repaired, but was DOA a second time in mid October. Personally delivered the unit to BenQ in early November and received a replacement which lasted for about 150 hours of use until it, too, developed a fault on a Friday evening in July 2013. So, on the Tuesday, back to Sydney it went a third time.
Fortunately, BenQ Australia offer a 3-year warranty with on-site courier pickup. It’s a great projector and I’m sticking with it. Shame about the reliability, but yay for the service: arrived in Sydney 4.30 PM yesterday, they fixed it today, it will be tested and returned tomorrow. And I'll get a phone call from the tech explaining what the problem was.
Anyway, while playing around with the sick projector over the weekend awaiting pickup, I thought I’d check the lamp. One thing led to another, and the lamp module was soon in pieces on my work bench. Then I wanted to find out technical details about the lamp, and that led to a 9-page PDF containing almost everything you’d ever want to know about a BenQ W7000 lamp and how to replace it.
