Audio Systems: nakamichi led, lexus gs300, radio cassette cd

Question
I have a '98 lexus/nakamichi factory-installed audio system in my car. Radio,cassette, cd player work fine but the led has stopped working.  Can't tell which radio station or cd selection I'm listening to.  Nakamichi on the web refers to lexus dealer. Do you have any experience with this? Thank you
