How to Fix the iPhone X Ear Speaker Not Working Problem

Sometimes our iPhone X ear speaker is not working and we don’t know why. We need to tear down the phone and take out the ear speaker module to check the reason. Previously we’ve demonstrated to you how to replace the iPhone X series, ear speaker. This solution works on all the mobile phone broken ear speaker issues. We don’t have to this because this time we find the ear speaker flex is broken. Here we will show you our repair steps below.

When we test this iPhone X ear speaker, we can see the ear speaker is soundless. All other functions are normal, such as the face ID recognition, the true tone, the cameras, etc. Here we assume the ear speaker must have problems. The iPhone ear speaker consists of the ear speaker and long flex cable ribbon. We need to take this module out to check the problem. Firstly, we need to turn off the phone and loosen the pentalobe screws on the bottom. Then we take the procedure of tearing down the iPhone X screen and digitizer. When the screen is removed, we unbolt the screws and take off the metal panel to take out the ear speaker module. The ear speaker seems normal. We need to measure the J4600 connector on the iPhone with the machine, we can see all the values are normal. We measure the ear speaker connector values. All are normal, too. The ear speaker has no problems, then we check the flex. Here we find a crack on the flex ribbon. This is the reason why the ear speaker not working. Base on the case, we need to solder a jumping wire aside the crack part to fix the issue. Use tweezers to scrape on the flex, on each side of the crack. Scrapping until we see the copper wire. Clear off the scrape, apply some soldering flux on the scrapes. Coat in the copper wire and solder a 0.009m jumping wire on the scrapped copper wire, jumping across the crack part. Apply some PCB cleaner to clean the crape on the flex. After the iPhone X ear speaker with flex cable ribbon is fixed, we need to install the ear speaker back to the iPhone. Tighten the screws to fix it. Assemble the screen back, connect the flex cables, and fixing the cables with a metal bracket and screws. Don’t forget to connect the battery cable. When the iPhone screen is assembled, we turn on the iPhone and check the ear speaker function. Now we can see it the ear speaker is working normally.

At last, there are some notices about the repair procedure above we need to focus on. The iPhone ear speaker flex is easy to be broken, we need to be careful on it while scraping on it.
