Repair Tabletop Jukebox lights?

I just purchased a Thomas Collector's edition CR-11 Tabletop Jukebox AM/FM Radio Cassette Player. It's very similar to the Crosley Limited CR-11. It was advertised as being in good condition and the lights were working when the Jukebox was listed. The radio and cassette player are working. So only the decorative illumination isn't working. I'm hoping someone can tell me how I might repair the lights. I looked online to see if anyone else had posted a similar question, but didn't get lucky. Yes I do know that I can send it back to the seller, but I would really like to keep i, and repair if possible first.
