MacBook Pro Touchbar /Mid-2017

screen was replaced at another shop, i haven't gotten the computer yet. but apparently after the repair the touch-bar stopped working, as i haven't had any experience with touch-bars yet i was looking for some guidance, what should i look for, what could cause it. im assuming something got broken off somewhere. but is there anything else that could cause this from replacing a screen assembly?

Probably knocked off component, or broken trace.
Check some voltages and signals on touchbar connector.
