The radio is silent, but the screen works
This is what the audio fault in MIB3 (Preh) looks like. The symptoms you describe help confirm it:
- no sound from any source — radio, Bluetooth or navigation,
- the radio crackles, then locks on to one tone and buzzes until the key is removed,
- after restarting, there is still no sound,
- the screen, touch function and reversing camera all work normally.
The problem appears suddenly: one day everything works, the next there is silence.
What does the scope of repair depend on, and what do we check?
We connect the removed module to our test bench and check the audio inputs, sound processing and outputs to the speakers separately. We prepare an initial quote in advance — based on the description and a photo of the panel and the label with the part number; also provide the make, model and year of the car. We do not repair units fitted in place of factory units, such as Android-based replacements.
After checking the module, we present the scope of work and the price, and wait for your approval before repairing it.
