Xiaomi Redmi 7A Sound Problem Repair Solution
- Test the speaker with a multimeter. Replace if damaged. Distorted sound is caused by weak speakers or damaged internal coils.
- If the speaker is good and there are no problems, make sure that the terminal is not biased. Then, clean the contact gasket of the buzzer connector to avoid possible oxidation (which can weaken the connection).
- Check each buzzer + and buzzer- corresponding connection path to each component where it is being connected.
- If any speaker + or - is missing then rephrase.
If the mobile phone has water damage problem. Try to find some resistor or capacitor that is missing, on fire or on its motherboard. You can solve it by re-soldering or replacing any damaged or missing 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 can 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.
