The car dash probably lights the radio dial so that it will dim down with the dash light dimmer. The radio light may still be switched on and off by the radio switch but its a separate circuit. Check the fuse for the circuit that powers the radio itself. It should have its own fuse. Its likely that the radio has failed and will have to be removed and checked on a bench but check the fuse and check the power and antenna connectors in the back of the radio as these sometimes come loose from vibration. Always replace a fuse with one of the exact same amperage, voltage rating, and time delay if any as the original. If a fuse is blown the cause may be internal to the radio or it may be a problem with the car wiring to the radio. If blown check the wiring leading to the radio for worn insulation near sharp edges in the dash.
