My iPhone 6 has no sound, how to repair it ?
One of my clients asked me for help. He bought a second-hand iPhone, but used it to find that his phone had no sound.
When you turn on the ringtone option on your phone, it gets stuck. Turn on the recorder and click on the recording item, but you cannot record any sound. What caused this failure? What measures should we take?
Facing up to the case, the possibility of a small audio failure is greater. Romoving the iphone motherboard, we obeserved that the large audio and the small audio have been replaced. As the case revealed, the culprit possibility of the chip itself is very small. Removing the small audio by iphone opening tool, and testing the small pad ground value of the pad, finding that the small audio F6 foot resistance is infinite (normally around 400)
This is the small audio I2S bus, to the big audio and CPU. If refer to the big audio, removing the big audio, if it cannot work, you can consider to change the big audio ic, test the pin connected with the small audio F6 foot, the value is normal, it seems that from here to install the jumper wire to the small audio is all right.
After installing the jumper wire, which is used to repair phone logic board, and assembe your phone. The sound is normal after testing, and the recorder can record normally.
