The big cooling fan makes a lot of noise, - What do I do ?


Hello
It may be due to some friction in its bush bearings. Take it out from the unit. Peel off the emblem on its center part slighly up, put a drop of machine oil to the center shaft point exposed. This must resolve the problem of your cooling fan. Brush out all dust accumuated on its leaves, if any, before refit it into the projector.
If this does not resolve the problem, the fan should be repalced with same type and voltage ratings. All these details will bw marked on the fan. It can be bought from most of the electronic spare part shops at your town, or from the authorised service center for BenQ at your town. If any leaf has borken, the fan will make noise. If so, it shoud be repalced. OK.

BENQ 5000 SCANNER DRIVER FOR MAC OS?


BenQ does not make MAC OS drivers for this model scanner. Only Windows XP on down to 98 are provided.
Maybe you could run XP in BootCamp, Parallels, or VMWare Fusion on your Mac and use the scanner from the Windows OS...?
Good Luck!

My benq projector keeps blowing lamps.


first, blow out any dust with canned air. dust keeps in the heat that the projector is trying to expell. next, don't buy cheap lamps from random websites. you get what you pay for. and make sure you have the correct lamp that the manufacturer states. also make sure there is sufficient space around the projector. the vents cannot be blocked. lastly, reset the settings to factory default. many times there is a low power/full power setting. the fans go on full on high power. there should be at least 2 fans. one for the lamp, one for the optical engine. may be one for the power supply. if the one near the lamp is not blowing much, replace it.

BenQ 8700 projector solution


Hi Rick

The upgrade is the same one used for the BenQ PE8720

Whoever told you this obviously did'nt know this.

You'll be needing Flashloader and the RS232 cable that came with the Projector.

It is absolutely cheeky of them to suggest that you should just use the Component input for all your applications on this Projector.

Make sure they understand that this was a top of the range Projector when you bought it and that it is not a good enough answer.
