I am cleaning and shopping out a Stern Monopoly. Game is playing very well and the playfield has come up like new. Only issue I have is the Mini DMD is not working at all. I have checked voltage at the board and also tried it out on a different Power Driver board. Still nothing, so I am fairly certain the issue is with the DMD. I have been looking all over at all the usual places to try to find a replacement, but to no avail. Firstly if anyone has a known working or NOS Mini DMD part no. 520-5197-00, at a reasonable price I would be interested in buying it. If I cannot locate one, I am tossing up the idea of building an aftermarket replacement. Any one else interested as without about 20 interested people, it is cost prohibitive. IF I could find 20 people, I could probably get the price to about 200 AUD each (about US$140).
