Introduction
If you have a crack or excessive burn-in damage on your Galaxy Tab S3's screen, you will need to replace the entire display assembly. You may also need to replace the rear glass panel if it is cracked. This guide will show you how to remove and replace both components properly.
What you need
-
-
To soften the adhesive holding the tablet together, heat up the edges of the glass panel using a heated iOpener on the edge of the device.
-
We used two iOpeners to open up the tablet. The process is doable with a single iOpener, but would take substantially longer. Alternatively, you can use a heat gun to quickly loosen the adhesive.
-
Leave the iOpener on edge for two minutes.
-
-
-
Place a suction cup near edge that you heated up with the iOpener.
-
Press down on the suction cup to create a seal, and pull up with force to create a separation between the display and the midframe.
-
Use an opening tool to split apart the glass panel from the midframe.
-
-
-
-
As you continue along the edge using the opening tool, use a plastic card to keep the glass separate from the midframe.
-
-
-
Pull off the glass panel using the suction cup.
-
Carefully disconnect the ribbon connecting the display assembly to the motherboard. You can disconnect this ribbon from either end.
