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 first to prevent the accident from happening

unplug all the cables before we remove any other parts of the keyboard

unscrew the small board （including 2 m2 4mm screws)to let 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

we need to connect the board to the computer, turn the circuit on then we will be able to test where the problem

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

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

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

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

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

Here is how to switch switches, first unplug the keycap

Then unplug the switch

after that plug in a new switch

Finally put back the keycap, then it is done for changing switches

congratulations you are done for the replacement, now put the board back, screw it with 2 4mm M2 screws, and connect all the cables back

When everything is done, just put back the top layer, then it will work same as the new one
