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.
- For more information on soldering, refer to this How to Solder and Desolder Connections guide.
