Introduction

Have you been experiencing distorted sound or muffled audio with your Toptro TR23? If so here is a step by step guide to replace the projector’s speaker. All you will need is the iFixit Opening Tool and a #1 Phillips Screwdriver heads in order to remove the screws involved in this replacement.

Before starting this guide I would make sure the wholes in the casing, that allow sound from the speaker to leave the projector, are free from debris. That where you have mounted the projector is not hindering the sound from being projected across the area you area you are using the projector and that, once the case is removed, the speaker cable is securely mounted to the motherboard.

Before attempting this guide make sure that your projector is unplugged from its power source and is on level sturdy work surface.
