Hi, I have a problem with radio in my car. What happens is when you turn on the radio you can hear the sound and in like 5-10 seconds it goes off. It repeats every time you turn the radio on. It is factory radio never had been removed, what can I do to fix it?

I'm sorry, I should've mentioned that when sound goes off, radio/cd player still working(lights are on and it shows what track its on and so on).
