Tools Needed: Phillips head screwdriver (optional – power screwdriver), Tweezers, Prying tool

Removing the old screen

First you have to remove two screws from the bottom of the digitizer (circled in green below). The digitizer is held in by clips on the inside and some adhesive along the bottom. Insert your prying tool into the top of the screen between the bezel and the case as shown in the picture below. Be careful to not crack the digitizer if you are just replacing the LCD screen. Also be careful of the digitizer cable that connects at the top left of the screen. Disconnect the 2 ribbon cable connectors when you have removed enough of the digitizer off to access it.

Work your way around the digitizer disconnecting it and separate the adhesive when you get to the bottom. The hinges are covered by plastic from the digitizer so use your prying tool to free them.

Once the bezel is removed, there are 4 screws (at arrows in blue in picture below) that hold in the screen that need to be taken out. When the screws have been removed, gently lift up the LCD screen to separate a little bit from the case. Don’t remove it entirely because there is a cable connected to the back.

Gently lay the LCD face down. On the back at the bottom you will find a gold connector attached to the screen. Loosen the tape covering the connector and disconnect it. Set your old LCD screen aside and get out your new LCD screen.

Installing your new LCD screen / Digitizer

With your new screens face down, reconnect the gold connector and replace the tape covering it. Then put the screen back into its place making sure it is fitting correctly. Next replace the 4 screws that hold in the screen. Then retrieve your old/new digitizer and reconnect it both ribbon cables to the top connectors. Finally, run your hands along the edges of the screen, snapping the bezel back into place as you go. Make sure the plastic covering the hinges is situated and attached correctly.

Now you can re-attach the LCD screen assembly to the rest of the the laptop. Check out our teardown linked at the top of the post for how to do so.

    As I’m guessing your in the US I probably can’t send my laptop to you to be repaired but was hoping there was an easier way to replace LCD without having to totally strip down my Toshiba satellite C50Dt-b just thought there would be a simpler way.
