Beats Solo 3 Left Hinge Replacement

简介

This guide explains how to replace the left hinge of the Beats by Dre Solo3 headphones. The model number of these headphones is A1796. A faulty hinge is one of the leading causes that render these headphones unusable. Although the hinge is a simple component of the headphones, this repair is not for the light-hearted and will definitely take some time and technical skill to complete.

Required special skills:

Soldering/desoldering the wires
Screwing/unscrewing the screws

Note:

Using a plastic or nylon pry tool is highly recommended when taking apart the device to ensure no damages occur.
Before beginning, make sure to power off your headphones completely and disconnect from any external power source.
Be extremely cautious when working around the wires because if they are nicked or damaged during the repairing process the device will no longer be useable and is a fire hazard.
