How to Fix the James Donkey RS2 2.0 Switch or Motherboard

The first step is to disassemble all the pieces to make sure all the parts are separated.

Make sure all the cable is unplugged to prevent an accident from happening.

Unplug all the cables before removing any other parts of the keyboard.

Unscrew the small board (including 2 m 2 4 mm screws) to make it easier to figure out where the trouble is.

Then plug it back into the PCB. What we get will be a small board connected to the big board.

Connect the board to the computer, and turn the circuit on to test to see where the problem is.

To figure out if is it connected or not, first open the key tester on a computer that has been connected to the keyboard.

Use the metal tweezer to connect the silver part under the PCB.

If everything works fine, it should light in green, which means the key has been sensed.

If there is just one single key that is unable to react, then switch it.

If there is a line that has no reaction, which means PCB is malfunctioning, send it back for repair.

Here is how to switch the switches. First, unplug the keycap.

Then unplug the switch.

After that, plug in a new switch.

Finally, put back the keycap.

Congratulations! You are done with the replacement. Now put the board back, screw it with 2 4 mm M2 screws, and connect all the cables.

When everything is done, put back the top layer.
