Introduction

Go to step 1

This guide goes over how to replace the controller's main circuit board.

If your TPC-Q044 circuit board starts failing when using your controller, you may want to think about replacing the component. The failure may be a result of bad soldering or missed connections. The replacement of the circuit board is not too complex. A couple of screwdrivers and a spudger will be sufficient to complete this task. There are no warnings or potential hazards when replacing the board.
