I have a 2015 Equinox LTZ. My radio screen went black. So after checking the fuses, disconnecting the battery and pushing the onstar button nothing changed. I bought a used one off of ebay, plugged it in and nothing! I would at least expect a "locked" screen. I purchased another working radio and still nothing. Has anyone else had this issue? We did check and power is getting to the screen, it's just not turning on. Wondering if anyone else had this issue and what they did to fix it.
Thanks!

 

Did you find a fix to this?? I have a 2016 Equinox LS and am having the same problem. We received our new screen from an ebay purchase and nothing. Help??
