Hi. My name is*****'m a camera repair technician with almost 30years in the business and I'll be glad to help you with your question today.
These projectors were manufactured by the millions but, unfortunately, parts are almost impossible to find. there may be a repair shop on another network I belong to who still repairs them. I'll be happy to check for you. It may just be a worn belt or bad clutch.
One of the repair shops on my network has responded and still does projector repairs. Their email address is listed below.
