Problem with OSP 3000 of Okuma LC10

[Dynamometer]

Hello,

I have problems with Okuma LC-10 OSP 3000 (1981) programming unit 7-segment display.

As you see on below link picture left upper corner 7-segments are not working : http://www.dynomec.com/okuma2.jpg

Here is another view inside unit : http://www.dynomec.com/okuma1.jpg

Schematics for 7-segment are here : http://www.dynomec.com/okuma3.jpg

A LOT of other files and pictures you may find from here : http://www.vauhtikauppa.com/Okuma.zip

Shortly the problem maybe is display data latching failure.

So, if anyone have faced same problem, please tell what could be wrong or which part to replace?

Does anyone know where to get spareparts?

Does anyone have IF12 board electrical schematics or any ideas where to get?

IF12 board is located on main cabin and is possible reason. It's serial number is : E4809-032-399-C

All advices very wellcome, I would like to get Okuma back running again.

BR,

Harri,

I have a call into a friend of mine that may have schematics and spares. Send me your contact info via PM. I'll pass it on to him if he does.
