Dear Community, I replaced the screen of my MBP with this LCD Assembly for Macbook Pro Retina 13" A1706/A1708 The screen works just fine, but the TouchBar does not react to touch anymore. It still reacts and shows the corresponding buttons to the programme I am using at a given moment. Also notable is, that I cannot find the TouchBar agent in the activity monitor. I tried already to restart the agent in the terminal and reset the SMC. I fear that I ordered a wrong screen or damaged it during the repair. Would appreciate any tips!
Sadly that leaves the only thing left is when you damaged the display the Touch Bar also got damaged too. The Touch Bar display is independent of the main screen from a connection perspective to the main logic board. The driver & touch logic is part of it: MacBook Pro 13" Retina (Late 2016-2017) Touch Bar Assembly.
hi, i just solved this problem. just remove the touchbar connector then reinsert it again, apparently mine was not connected properly. i really dont know how it was unconnected since the screen replacement did not touch this part. but anyways give it a try.
@pestarzt Did you ever figure out what happened and how did you fix? I just replaced the display assembly on my mid-2017 MBP 13 w/Touch Bar and after reassembling the screen worked fine but, the Touch Bar would not respond to touch. It did however, display the commands, options etc. as expected.
Hi @pestarzt , I have the same problem as yours, did u figure out how to fix it?
this is the second screen replacement I’ve had this happen to, but it looks like I’ve fixed it. I’m a repair shop so I have access to just the touch bar module. Just to see what happens, I disconnected the battery, connected the new Touch Bar (just the digitizer, the lcd is under the board). Booted it up and the touch works on the new bar. Reversed everything and connected the old Touch Bar, and everything works again. Hope it’s a permanent fix. Works after a restart, too. Edit for clarification: you need to have another Touch Bar module on hand. This is the 10” strip of glass that houses the digitizer and OLED. You will need to order one from your favorite shop. Connect the new module to the computer, just the digitizer connection, you can leave the OLED connection for the one still attached the the keyboard. Boot the machine, test the external TB module touch, if it works, turn off machine and reconnect original TB digitizer connection. That’s what worked for me.
I experienced the same problem and the solution in my case was to clean the touchbar connector with a toothbrush, you don’t loose anything trying, hope it works for you too.
Replaced more than 10 screens! of 2017 Macbook Pro’s, which is basically the same as 2020 M1 screen, never ever had any problem! This is my first M1 Macbook and the TouchBar won’t light up with the new screen. It’s responding to touch, but no backlight. Fitted back the old broken screen, TouchBar working just fine. So, I isolated the issue down to a firmware/software problem, nothing to do with the TouchBar itself… Still no solution… Update (11/10/2021) I was able to reset the TouchBar with terminal command, and now it’s fine!
Hi, I have the same problem here. Can someone send me a picture or link to identify where the Touch Bar connector is, so I could try to unplug and replug it. Thanks for the help
