Hello,
My car speakers catch electric disturbance producing awful buzzing noise.
When I put different radio module the noise disappears.
I have now two modules for repair with different problems.One is picking up noise the other works fine but it looses radio stations and stops working when it wants.
I am trying to repair the noisy module by comparing it to the working one but I cant spot significant difference in capacitance and resistance when testing the voltage regulators and capacitors.
I removed the big capacitors around the voltage regulators and all tested within spec.
Do anyone have idea which components could be responsible for noise filtering?
