I have a PT-Ae900U that I just replaced the original bulb. Inside, the prism was filthy, so I wiped it gently with a cloth. When I started up the projector, I noticed there was still a lot of dust on the inside of the lens.

Is there a way that I can clean off the dust?

On the old bulb, there was burning or discoloration, resembling the corosion found on a tintype that was in the sun. I fear that a similar fate may exist inside my lenses. Is that possible? If so, how do I go about cleaning it?

Also, where can I find a safe download of the Service Manual to aid me in my task?

Try this and see if it would help, though a different Panny model. It worked for my old ae500.

I tried opening the case and blowing canned air through the three holes where the ribbons attach. I carefully vacuumed everwhere I could. I also tried to blow as much with canned air as I could, without taking anything other than the lid off of the unit.

I still have a build-up of dust inside the lenses. The projector is now 5 going on 6 years old, so it isn't under warrantee.

Any suggestions on how I can get the dust from inside the lenses? I doubt there is a service center nearby, but if there is, how much would I expect to pay to clean it up?

You keep saying "inside the lens". Is this dust that you actually see inside the projection lens? And do you see dust in the image?
