replace one or two of the IGBT 's on your motor control
board.
The IGBT 's also called MOSFET N-channel are:
IRFP 450 International Rectifier.
You can buy these from conrad.
This repair worked for me and I have a strenghtmaster MA-200X.
Also check the probably 10 ampere fuse after repair on
your MCboard.
The price is about euro 3 each.
