Got my first digital projector yesterday. I finally splurged on a BenQ W7000, a special from a dealer in Melbourne. When I first turned it on it went through about a minute of setting up and projecting, then the "Temp" light came on and the lamp went off. Before that happened, I was successfully playing a DVD. I have been through the process about a dozen times now, without the DVD connected, and each time the lamp turns off and I have to wait several minutes before the W7000 will start up again. I tried removing the power completely for a couple of hours, but no matter what I try I get the same result. At all times, the projector and exhaust air were barely above ambient temperature.
Something strange happened once: a very loud, rough, fan noise came from the unit. I noticed that if I pushed the power plug in gently, the noise would decrease, and if I pushed firmly enough, the noise would almost stop. That problem hasn't repeated itself.
I rang the dealer and said I wanted another unit. No problem there. He emailed me with this:
I've just got off the phone with BenQ. Looks like the heat sensor would have tripped. They have recommended to unplug it completely from power for at least 5 hours (they suggested overnight). Then plug it in and it will reset. If you're still having trouble e-mail me and I can get a DOA organised.
His colleague during another call suggested that the lamp was turning off because I didn't have a signal connected.
I would like to know the answers to some questions, from someone who has experience with the W7000. The sales staff were doing their best, but I got the impression they knew little more than I did about the W7000.
Q1: Is the tripping of the heat sensor a common occurrence, and would it take five hours to reset?
Q2: Will the projector stay turned on if there is no external signal? Or will it turn off after a certain time?
Q3: Any suggestions as to why pushing on the power plug would cause a loud grating fan-type noise to become less? Or what the noise could have been in the first place?
Any comments most appreciated.
