Introduction

The power button is a switch used to turn the device on and off. The mode button changes how the toothbrush will vibrate. If you are having problems with either of these functions these buttons are likely the cause. There are small components in this guide so a steady hand is suggested to not damage other parts. Exercise caution when using the soldering iron as it is very hot.

Step 5

Heat the soldering iron.
Soldering can cause burns and fires. Always solder in a well-ventilated area.
To test if the soldering iron is ready, place on the solder and if the solder melts easily and quickly, your soldering iron is ready.
Use the soldering iron to desolder all of the connections.
