Fixing Late 2016 MBP #flexgate

A couple of weeks ago my 15" MBP from late 2016 started showing signs of #flexgate. Please Google it! In short, the backlight flex cable connecting the main body with the screen is too short by design and breaks in a couple of years of normal use. Just around the…

DIY Eurorack case
