I work for K-Tec Earth Movers out in Canada. I am inquiring about what it might cost to repair a Siemens Kaeser 6BK1200-0AB20-0AA0 control unit. The lights on the sides are on, but there is no display or any functionality of the buttons. I measured 24volts to the board so that is not the issue. We are located in Rosenort Manitoba Canada. What kind of turn around would I be expecting for the repair to take? Thanks.
