Black nexus 7 screen

[Chris2016]

I just got a new screen/digitizer for my 2012 nexus 7, and after the replace, ill press the on button, and the screen does nothing, if i give it a minute and tap on the screen, ill get the sound you get when taping on this so i know its on and the digitizer works, but the screen never shows anything. Anyone have any ideas on how to fix?

Thanks
