BENQ MP515 Projector showing dots on projected image
I'm having a weird issue with a Benq MP515 Projector. The projected image is showing little white dots at random places on the screen as it starts up, which then change to little black dots once the image from the PC is projected.
It's still workable with but I'm trying to work out what to do with it. I've checked cable connections, cleared out as much dust as I can from the outside and the next thing would be to get it out of it's N-Cage (I hate those things!) and open it up for a good clean.
I emailed Benq's customer support and they advised the projector's DMD chip might be failing and it will need a service.
It'd seem a shame to have to repair / replace it when it's OK apart from these little dots.
