I replaced my 2018 MacBook Pro (A1989 EMC3214) screen which I bought on Ebay stating its an exact match by a guy that sells them. Like a lot of these people on that site. Questioned and stumped. I have No Touch Bar nothing lights up or functions, and yes I did reset SMC & NVRAM. Called Apple to remote in and went to Apple and I got no where I figured. I was very careful 1st time ever to do this and I did not disconnect cable off touch bar but heard that Apple has a block on 3rd party replacements? Is there anything on the replacement display that controls the touch bar? Newbie is me for sure HELP ANYBODY I didn’t have an ESC key, it’s an assigned one on touch bar that is the biggest issue in having the13” Touch Bar model.
I would go back to the supplier of your display as something doesn’t sound right here. I’ve replaced a few 13" & 15" Touch Bar displays and I have not encountered messing up the touch bar. Are you sure you followed the guide correctly? did you disable Auto Boot before doing anything and well as disconnect the battery? Did you use a proper ESD practices? Static can damage things! The only issue I’ve faced is True Tone not working after replacing the display as the display was either the wrong one or one that was not calibrated before leaving the factory.
I have the same issue, is it due to display comptibility?
