What would make the radio in a 2001 cut out? It has a 3 band equalizer that would light up but nothing happened with the radio, not even when the fuse was removed. All of a sudden, the radio decided to work

. But the battery was dead.
Changed the battery and the radio worked for a few days and quit working when I went to turn up the volume. It comes on, sometime, but cuts out as soon as the volume knob is touched. Any suggestions?
