Introduction

The HTC Vive controller trackpad may be faulty from extended or rough use and not detecting your fingers properly. The daughterboard interprets trackpad input and is solely dedicated to the trackpad's function. Minimize surface contact with the daughterboard's circuits. This guide will show you how to replace the trackpad daughterboard.

Turn over the Vive controller so that the bottom saucer is facing up. Use the T5 Torx screwdriver to remove three black 21mm screws from the bottom saucer. Use the T5 Torx screwdriver to remove three black 21mm screws from the bottom saucer.

My top saucer was REALLY stubborn. Don’t force it with your hand, use the spudger to separate it at the seam. Try not to poke your spudger in too deep, there are internals just inside the seam.

The second time around, I learned why it was so stubborn. The picture suggests that you should start at the base of the saucer and work your way around, but that’s backwards.

Start separating with your spudger at the distal side of the saucer and work your way toward the handle. Then for the last part, pull the piece up and away, like peeling a banana. See the second picture for the bottom half of the saucer, below. Do the same on the top.

It’s Phillips 0, not 00.

Leave the middle screw where it is (the one being unscrewed in the picture). That screw holds the two halves of the photodiode assembly together, not the case.

Hello, today I’ve broke my controller, and the daughterboard has lived and deconnected. After, I tested to connect it and power it on, but no sound and he’s not tracked, can it get repaired?

This guide is nice, but where do we find the replacement parts ?
