Replacing The Lens On A Mp772st
I currently own a BenQ MP 772 ST proector with a scratched lens. I would like to order the lens and replace it myself, but I don't know if this is something I can/should do. The projector is not under warranty so I think taking it to a repair center (or sending it back to BenW) will probably be expensive. I found a couple of places online where I can purchase a replacement lens but I haven't found any information about replacing it. Has anyone else tried this before? Is it hard to do? Is there anything I need to watch out for while I'm digging through the internals of the proejctor?
