New Moto z Play lcd unresponsive

Following the iFixit guide I carefully removed the LCD assembly from my Moto Z play now the new assembly is completely unresponsive the old display was broken but with my projector mod it would respond to touch I tried reconnecting the old display now it won’t respond, all I connected was the wide ribbon cable for the LCD I’m guessing that’s all that is needed to test the new LCD I had no issues replacing it, I’m missing something somewhere? Any ideas?
