iHome iH9 Volume/Tuning Dials Replacement

简介

Is your device's dial sticking or not rotating at all? Access either the tuning or volume dial located on the top of the iHome iH9 using this guide. From there, you can clean the dials or replace them if they are broken.

It is best to do this on a flat surface with plenty of space. This replacement involves removing many screws, so keep track of them to ensure easy reassembly. You can organize the screws by placing them on a magnetic pad immediately upon removal.
