If your ZTE Tempo smartphone (model 9131) has poor sound—distorted, cutting in and out, or no audio at all—through headphones or auxiliary speakers, this guide will show you how to replace the headphone port (also called a jack).
The headphone port sends audio to external speakers through an aux cord. A faulty headphone port will transmit distorted audio or no audio at all.
Before using this guide, inspect the headphone port for debris that may be interfering with sound quality. Typically, a small buildup of dust can be removed using an ESD-safe brush or small dust blower. Be sure to test a few sets of headphones or auxiliary cords with your device to confirm that the faulty part is coming from the ZTE Tempo’s headphone port.
In Step 5, you’ll remove the circuit board from the device. From there, you will need to desolder the surface-mounted headphone jack and solder a new one in place.
Before beginning, make sure to power off your phone completely and disconnect from any external power source.
