The problem could be the Power Supply, Mother Board, Tools Carriage or connection.

You need a Multimeter or a similar device to identify the problem.

If you can, please test the Tools Carriage input DC voltage.  Remove the square plastic cover of the Tools Carriage, you will see two large soldering points.  They are Tools Carriage input.  The tools carriage input DC voltage depends on the force setting.  It will be between 0 to 11 volt DC.  When you press and release the origin button, the blade should move up and down, the input DC voltage should change from positive to negative; or negative to positive.  The up voltage should be always around 3.1v.  If you set the force to 200, the down voltage should be around 5.8v.  If you can get the correct tools carriage inputs, you need to replace the tools carriage.

If you canít get the correct tools carriage input, please test the mother board output.  Remove the right plastic cover.  Usually it is a two pins connector on the lower right corner of the mother board.  Disconnect the two pins connector and test the pins on the mother board.  If you can get the correct mother board output, you need to check the connection between the mother board output to the Tools carriage input or replace the whole cable.  

If you canít get the correct mother board output, please test the Power Supply output(Large 5 pins connector in the upper right of the motherboard).  The Power Supply output should be Ground(Black), +5v(Red), -8v(Green), +18v(White or Yellow) and +36v(Blue).  If you canít get to correct power supply output, you need to replace the power supply; otherwise, you need to replace the motherboard.
