Maho 600 cnc432 major problem

[Jitze]

Hello the next problem has occured with a maho600.
When i turn on the power the display shows some parts of text on the screen.
On the upperleft is "manual" and the upperright is only a "2".
Below there is says MAN-OP and where the axis are there are a lot of zeros and a big value. the G- and M-codes are also displayed.

I cant get in speicher (memory) mode.
But when i remove the diagnosis-card i can see the in and outputs.

I already extracted all the ic's and cleand them.
Cleaned the backplane and the panel.


So i dont know what to do anymore.

regards

Jitze
