To repair the Xiaomi POCO M3 Speaker Problem, you can first clean the contact pads of the speaker connector on the PCB board if there is corrosion or oxidation. Then test the speaker with a multimeter to easily determine if it's working. If the speaker is confirmed to be ok, you can refer to the solution below and perform the check and test procedure on some components that are linked or connected to the external speaker circuit.
If the mobile phone has water damage problem. Try to find some missing, burning capacitor or resistor on its motherboard. You can solve this by re-soldering or replacing any missing or damaged parts before replacing. Some timing headphones and its precise points are working fine. But the bell in mounting with the front panel has connection problems. In this case, you could try a wire that connects directly from the speaker's pins to its retaining pins. I have fixed this problem many times by re-soldering the latches of the speaker cushions.
Solution to fix sound problems on Xiaomi Poco M3
- Test speakers with a multimeter, replace if damaged. Distorted sound is due to weak speaker or it has burned out (internal coil is damaged).
- If the speaker is fine and there are no problems, make sure the terminal is not biased. Then, clean the speaker connector contact pads to avoid possible oxidation (which could weaken the connection).
- Check each speaker + and speaker - connection line path respectively to each component where it is being connected.
- If any + or - speakers are missing, then create a jumper.
There is no external microchip to control its incoming voice. There is no volume level option to equalize incoming caller's voice. You can do a little repair by cleaning the motherboard. Don't forget to dry your mobile phone motherboard after cleaning with electronics cleaner.
