I have the same issue but mine is due to me damaging a little chip near the connector. Maybe check your board over and make sure you didn't damage any chips in the process like I did

It does work, I did this with my own Mac and you can remove the screen and keep the functionality of the touch-bar. What you will loose is keyboard backlight so make sure that the brightness in software is at 100% for the touch-bar to be full brightness cos that won't change when you take the screen off

Ok so I would like to inform you that I did a little bit of digging into my MacBook Pro with its Touch Bar connectors and I have made the discovery that 1 one of those little chips near the connector I think they are resistors or diodes, idk but I found that one of them have literally exploded and killed another one next to it. I have no idea why or how but maybe you wanna check your MacBook Pro for that as well to see if its a common occurrence

I mean you may as well because what if it is just some simple calibration issue or some silly little thing that their diagnostic software can fix in less than a minute? If they try to charge too much money then you can always just deny, I believe that I will end up doing that soon to get a quote on just how much it will cost me to get both the display and Touch Bar repaired and see if it is worth it or not.

Like I asked the other guy, did you ever manage to find a fix for it? Because I am too having this issue

Did you ever find an answer to this because I have had the same thing happen and I cannot for the life of me figure out why it has happened, what did you do to fix the problem or did you just give up and go to apple?
