2004 Chevrolet Suburban Radio power button

I just replaced the radio power button because it was worn, and now the radio won't turn on. It did work before I replaced the button. I bought the replacement button from the Chevy dealership and it does fit. Can the radio be turned on another way? I can control the volume with the buttons on the steering wheel, if I could get the radio turned on to begin with. I put the old button back on and it doesn't work either.
