Step 2

              Remove the back lid
  • Use a small flat-headed screwdriver, spudger, or similar to pry open the lid enough to be able to get a grip of it and pull straight back and then fold down.
  • The back of the lid has a PCB with cables connecting it to the motherboard inside the unit. While not particularly fragile, do take care so you do not damage the connectors.

Step 3

              Remove the LED and power connectors
  • Remove the connectors by pulling them straight out.
  • Make sure you connect the connectors in the correct sockets during reassembly!

Step 4

              Remove the resin panel connector
  • Use a spudger or similar tool (your finger nail works if you can get it there) to loosen the resin panel connector by flipping the dark gray part 90° down.
  • Pull the cable straight up.
  • Be careful not to bend the cable!

Step 5

              Remove the bottom right connectors
  • Remove the three cable connectors in the bottom right corner by pulling them straight out.
  • Be sure to pull the connectors, and not the cables!
  • If you are also replacing the limit switch, now is a good time to do so.

Step 6

              Unfasten the motherboard
  • Remove the two screws fastening the motherboard to the unit.
  • 7.5mm self tapping screws with 2.0mm hex socket head
  • The touch screen cable on the right and the USB cable on the left are still connected to the motherboard.

Step 7

              Remove the tape covering the touch screen connector
  • Use a pair of tweezers to get a grip on and remove the tape covering the touch screen connector.
  • You can transfer this tape and reuse it on the new motherboard.

Step 8

              Remove the touch screen cable
  • Use a spudger or similar to unlock the connector by pushing the dark gray part to the right, away from the connector, both on the top and bottom.
  • Note how far into the connector the cable is seated. When reinserting the cable in the new motherboard it can be hard to feel if the cable is fully inserted.
  • Remove the cable by pulling it out of the connector to the right.

Step 9

              Remove the USB cable
  • Unplug the USB cable.
  • In my case the glue did not stick to the USB cable, just the USB socket on the motherboard, so I was able to just pull it out without doing anything with the glue. If necessary you should be able to pry off the glue blob with a spudger or similar.
  • During reassembly it is not necessary to glue these together.
