8 track player won't work?

[Recian]

So I pulled a lot of parts from a suburban today for my 81 c10. Figured I'd grab the radio since my radio's rear outputs don't work. It had a strange radio and when I got into it turns out it's an 8 track player with a digital display. The player will control all 3 speakers, the fader and balance work great but it's not picking up any stations and the display isn't lighting up. THe knob on the right should be the tuner and it's clicking while it turns but no changes. Pressing either of the 2 knobs will turn the radio off. Anyone have any ideas?
