Boss DR-880 Drum Machine Backlight

Hello, I got a Boss DR-880 Drum Machine from Craigslist. It’s great, works fine – all except the display’s backlight doesn’t work. I’ve tried all the “settings” fixes with no luck. Definitely seems I need a new part, but I can’t find info on it or anyplace that has it. Any suggestions? Thanks!

I have the same problem and have been searching for years.No info or fix.Great drum machine tho
