Touch bar on macbook pro doesn't light up, but still works if I click on it. How do I fix this problem? I've tried to restart the macbook a few times already

Try resetting the SMC https://support.apple.com/en-us/HT201295

if no resolve...

Even though SMC controls the touchbar, some USB is in play, so this would be NVRAM (or reboot.) notice among others:

USB Device: Apple T2 Bus

USB Device: Touch Bar Backlight

USB Device: Touch Bar Display

USB Device: Apple T2 Controller

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

If this does not solve your problem, I suspect your hardware issue needs to be resolved by Apple service:

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
