If you take an Apple product like an iPhone to an authorized service center to fix the screen it may take 5 working days or more to get your MacBook Screen repaired to work properly. Generally, People do not go to authorized service centers to fix their MacBook screen as the price of Mac-book screen replacement, MacBook Keyboard replacement, MacBook Battery Replacement, etc. is very high as compared to the open market and time taken by them to fix the screen. This is not worth it at all. In the open market, any third-party company can fix or replace the display within a few hours at a very nominal cost as compared to Apple authorized service centers in any city.
