Introduction

Before reviewing this guide, please see our troubleshooting page at Marvel iHome MR-M66 Troubleshooting. This page will allow you to view all common problems as well as likely causes to find the right solution for you.

The part being replaced in this guide, the speaker assembly, is essentially the channel that allows the audio output to be heard by the listener. By removing the old speaker part and replacing it with a new one, you will give your speaker the chance to play your favorite tunes again. Without replacing the speaker assembly, your speaker will continue to produce irregular or no sound.

It is important to note that this replacement process requires work with small wires and handling of the battery. Due to this, be sure that your device is powered off before beginning the repair.

What you need

Step 1

              Back Cover

Remove two of the three screws shown on the bottom of the device.
Begin removing the last screw, but leave it partially in the socket to remove the bottom cover easier.
