Urgent help needed on Mitsubishi MDSASPJA75RT

Good day Guy"s
Does anybody in the forum know where i can send a Mitsubishi MDSASPJA 75 RT Spindle drive for repairs.?
Got quite a few machines (Quicktec vmc ) in South AFRICA with these drives that goes faulty and there is nobody here that can REPAIR them.
Most of the faults are displays that does not switch on.(Segments on drive).
I can repair some errors on the MR-J2S series drives , but the MDS is another story.
Any info , not replacement , will be appreciated.
Thanks

I am glad to say i can now repair most of the problems on these Mitsubishi MDSASPJA75RT drives
