PRM-10 locked focus wheel
I purchased a refurbished PRM-10 and while it works well for the most part, the tab on the focus wheel will not turn (and from the look of if isn't designed to turn, it's one solid piece). Disassembling the projector, I found a internal focus wheel that was locked in place with a black Y shaped bracket. Removing this and turning the wheel from the inside results in the focus changing but only very slightly. How can I go about focusing the projector? At the maximum focus on the internal wheel it's very blurry and is focused extremely close to the lens, perhaps around 18 inches. Does anyone have any ideas about what might the happening here?
