Replacing a damaged laptop LED screen can be done by following a few simple steps. If the screen has a very fine crack on the edge, you can continue to use your laptop as usual, although it's best to avoid putting any pressure on the screen. To repair a physically broken or cracked screen, the only option is to replace the screen and restart the laptop. Close the laptop and reopen it.
Try to peel off the stuck pixels. Check the screen and backlight connections. Connect your laptop to an external monitor to make sure that it's really the screen that's broken and not something deeper. If there is no visible damage, but the screen behaves strangely, you can try connecting an external monitor to your laptop.
Repairing a basic laptop screen yourself is easier than you think, but if you have a specialized laptop such as an Ultrabook, a two-in-one or a MacBook, it's best to consult an expert. Malfunctioning problems may require more training.
