Radio Display Light Dark

I have a 2001 Grand AM GT with a 3.4L engine, 75000 miles and a Monsoon sound system.

I just recently bought this car from someone and the Radio display light is dark. If sunlight is on the display, information can be read, but this is the only time. I was wondering if this can be fixed by either switching out a fuse, replacing the bulb (if it can be replaced), or if I need to get a new radio altogether.
