Touch bar not lighting up... UGH!

Same issue, Touch Bar disappeared but invisible keys are still working... I had the laptop just 2 days ago 😟

I've checked most of the forums and i found some solutions suggestions that:

- pressing to Fn keys will bring back the buttons. Not working.

- reset the SMC and NVRAM. Not working.

- refreshing Touch Bar. Not working.

and some ideas about the problem:

- Maybe it is a second screen (using Usb-c adaptor with) problem.

- It's a software problem which couldn't fixed about 3 years by Apple 🙂

So my Touch Bar's screen went off and no solution that i can do. Best option is to take the laptop to the Apple service. As far as i understood from the other people who done it before, Service's are changing the parts but can not fix it. And some users report that this problem exist till this crap Touch Bar added to MacBooks.

So this should be a very big issue to Apple but no any respond or a single word.

Still nothing found for this problem... 😟

Same here, Fn function, Reset memory, reset here and there, nothing works so far.

All the invisible keys are still functioning, just that it does not lit up.

Everything starts to go downhill since change of management. Sigh

Same problem. I have Macbook Pro 2017, arrived 2 days ago and suddenly touch bar disappeared and couldn't find how to fix it.

Does anyone know if there is a settings about it or is it a hardware/software problem?

Thanks in advance...

I'm in the same boat as Kozmonot. Tried all of the same (fn key, resetting SMC and NVRAM). Next up, reinstall the OS which I just updated to 10.13.1. My touch bar neither lights up nor do any of the keys work.

Any replies from Apple yet?

I'm having exactly the same problem. Nothing seems to happen.

What I notice is that when I turn on the computer the touch bar lightens up all white for a fraction of a second and then never turns on again.....

URGH me too!

Anyone from apple out there?

I've had that exact same thing happen on a couple of occasions but I am currently having an issue where some of the icons that should be showing on the touch bar go black (search, volume, lock and siri) and when I press where I know they are they will light up. I've even had it were the entire touch bar goes black except for the escape key on the far left. This just started happening about a week ago, so about 4 weeks into it's usage. Are you having this issue too?

I have the exact same issue. I'm pretty sure that mine is only happening when I'm connected to an external monitor...
I had my first laptop replaced because of an issue with the USB-C ports. My original and replacement have the same issue. Please contact AppleCare if you haven't so that they can get more info from different machines. They collected many log files from both of my laptops, but I'm yet to hear anything back from them (I should probably just call back). I've also uploaded several videos of the issue to the cases that they have open for me.
I've found certain situations where I can consistently reproduce the issue - in iTunes when watching an iTunes U course is one of them - every time the touchbar sleeps, I wiggle the mouse and the touchbar flashes all weird and esc and control strip are not visible, and the scrubber area is all messed up too.
My specs, just for comparison:
15" touchbar, 2.7, 512GB, AMD 460, 10.12.2

It is worse for me too after it has been disconnected from an external monitor (the fancy LG 4K). The remedy is to open the macbook before unplugging it from the monitor. But alas, over time the touch bar exhibits the same issue until restart.

Same thing happens to me.

Was any of you able to fix this? Any specific apps that trigger this?

Nothing from resetting the SMC to pressing fn to rebooting the computer or any of the above work. The keys are not illuminated, and they do not function.

I have to admit, I was deeply suspicious when I saw the concept. Irritated that this set of core functions can flame out like this. ***.

A simple fix here is to press the fn button

After a troubleshooting session with Apple support on Wednesday, my issue has been resolved. They had me reset the SMC.

Yup, same problem here. Restart works but the problem always comes back after a while. Renders the bar useless when you have to guess where the buttons are!

Sounds like a workaround not a fix. I did call Apple Support the other day and they had me reset the SMC. That seems to have fixed it...at least for the last 48 hours.
