Is your brand new MacBook Pro experiencing display backlight issues? Is the display not working, screen not lighting up anymore? Do you have to close and open the display to turn the backlight On?

MacBook Pro Display Backlight Not Working?

This issue has been first mentioned by Eugene in the comments section of our macOS Monterey 12.0.1 review page:

“New 14-inch MacBook Pro 2021 here. After update to 12.0.1 from 12.0 my screen backlight turns off after I type password to unlock booting. I see everything on screen like pictures and dock but no backlight…”

I’ve researched the web and couldn’t find any other similar reports.

However, it seems that some units of the previous 13-inch MacBook Pro model manufactured between October 2016 and February 2018 have shipped with a display backlight manufacturing flaw!

Apple actually offers a service program and fixed affected units free of charge! Hopefully, we won’t start over!

The older MacBook Pros packed a delicate flex cable that was exposed to wear and tear after opening and closing the display on affected devices. A similarity to this 14-inch MacBook Pro 2021 report is that affected models are the smaller sized 13-inch ones.
