Phone Audio Circuit Repair in Kampala
When new speakers and microphones don't fix a sound problem, the fault may be in the phone's audio circuit. We diagnose it at board level instead of replacing parts at random.
Signs of this fault
- No sound from any speaker
- Speaker button greyed out during calls
- Callers can't hear you with a new microphone
- Voice notes record silence
- Phone slow to start with audio errors
How we diagnose it
- Test each speaker and microphone separately
- Swap in known-good parts
- Measure audio lines on the board
- Inspect the audio area under the microscope
What usually causes it
Audio IC fault
The audio chip or its connections can fail, often after drops.

Flex and connector faults
Ruled out first.
How we repair it
Failed components or connections on the audio circuit are repaired under the microscope and every audio function is tested.
Limits
Audio chip repairs vary by model; we confirm feasibility after diagnosis.
No fix, no fee. If we can’t fix it, you don’t pay. Every repair starts with a proper diagnosis. If we can’t repair the fault you booked for, there is no charge for the diagnosis or the repair attempt.
Common questions
My speaker button is greyed out during calls. What does it mean?
