the radio light did not come on but the radio worked

The radio illumination is usually on the same fuse as the rest of the dash lights. If you aren't having issues with other lights illuminating then it may be internal of the radio. If you bring it in to one of our certified repair shops, they can inspect and recommend remediation.
