Has anyone had any problem with their radio? Was working fine, but during a thunderstorm, it popped real loud. The radio still works, but the left side has a constant buzzing and loud crackling. When you first turn it on, the right side comes in clear, and then the left fades in along with the noise. I got another radio at the junk yard, but it does the same thing... The speakers seem to be okay. Running the balance all on the right side does not eliminate the noise. Any help would be appreciated.

 

Might be a ground problem.
