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?
