Hiya folks, I finally thought I'd ask about this little problem I'm having with my BenQ W1070. In pure black images, I see circular, slightly grey blobs, and about six of them and I see a new one at least every one to two weeks, it's a bit worrying. There not there at all with normal images, even a pure grey image, but even though it's only visible on blacks it's still can be a wee bit distracting.

Has anyone an idea what it is for sure, and can it be fixed at all? confused.gif

None at all? I've been doing a little reading on the subject here before I posted and it might be "dust blobs"? I believe that is dust behind some specific part of the lens? I hear mention of dust on the bulb can cause this too.

Would I need to open my projector up?

Could be some dust has got into the optical path but since its a DLP unit I kinda doubt it!!-- Bohanna

I should probably mention that each one of these circles seem to be all equal in size. If it was dust surely they would be all kinds of odd shapes.

I would contact Benq, something has clearly gone wrong and I don't think many here will be able to help you.
