Hi,
There is a chance the backlighting has failed in the radio. However, let's check a few things. First, is all interior lighting working in the vehicle? I ask because the radio illumination power is supplied by the interior lighting system.
If you look at pics 1 and 2, they show the wire color and pin identification at the radio to check for power. Note the wire is solid yellow.
Check that wire for power. There is a splice before the radio that may have failed and there is no power reaching the radio.
If there is power, suspect the bulb is bad.
Here is a link you may find helpful when checking the wiring:
