I was wrong, that screw is hooked to a motor under the screw. It raises and lowers the first lens over the CCD and i think this is the fine focus. It must of been dropped and the whole time it was actualy just a connection problem to that motor so it wasnt moving back into the right position when the lens retracts.

Took 3 days for me to figure it out but i got it. A510 self portrait.
