Dear Ladies and Gentlemen
I am in southern Africa Zimbabwe. I run a surfacing lab with old coburn machines 506 polishers ,103 lap truer 108 generator and 2113 generators.
The coburn 2113 was not booting properly and the power supply was fixed for the on board computer. The machine no longer boot. It only displays a dash on the screen. The cross curve and the spherical units are not initializing to 10.00 and not responding at all. Contacted the coburntechnologies and they said they are no longer supporting out dated machines. Can any one who have experienced the similar problem assist. Someone said l should replace the black box. Where can l get it? All your suggestions and ideas are most welcome
