You will have to have the fault codes checked/read out to see what codes are set.This needs done with a scan tool or computers that will plug into your vehicle and can communicate with all computers in your vehicle.Once this has been done any codes set (which there should be at least one code set) will need to be diagnosed to locate and repair this fault here.
I have seen issues with the sound amplifier as well as the radio itself cause this type of fault here needing replaced.Having the codes checked and further testing will help pinpoint the cause for repair here.
