Question about BenQ PB6100 Multimedia Projector
How do you safely clean the optics of a 6100. I can see dust particles on the inside of the lens (looking through the lens at an angle). I cleaned the lens on the outside with a camera lens cloth but don't know how to approach cleaning the lens on the inside. Thanks!
Hi Nutty Prof
You will have to open up the unit by unscrewing the screws at the bottom and taking off the top cover of your PB6100.
Right behind the lens is the Lightengine ( where the dust collects )
Take off the cover of the Lightengine by unscrewing the two screws at the top of it . Then blow out the inside of the light engine with Air in a can ( available from most good PC shops )
and then reassemble.
If the dust particles still show after this ( which I doubt it will ) then you will have to take it to a Service Centre to get cleaned out as you will not be able to reassemble the lens once taken apart - it is a HUGE job !
Thanks for using Fixya and Good Luck !
