I have this projector finally working and when I projected an image it was very cloudy,I cleaned both ends and it made no difference.
lens: Zoom Lens f/1.4 F: 20-32 mm
I'm not new to this stuff so I had a look through the lens,one end looked OK but the other end I can see tiny "bubbles",they must be on the internal lens?They were clear unlike mold.
I have more than a dozen lenses from dumped projectors,one almost fits and I did manage to get a sharp image,others were too small or too big!
What's my next step?
