Samsung A7 (2018) SM-A750FN Display Replacement

Turn off the device.

• Remove the SIM tray.

Careful: the back cover is fragile glass.

• Apply a heat gun to the device's rear to soften the adhesive securing the back cover.
• Use a suction cup to lift the back cover from the frame and insert a tool (pick or plastic) for separation.
• Pry around the entire cover to separate it from the frame.
• If adhesive remains stubborn, reapply heat for additional loosening.

Remove 7 screws on upper half of frame.

• Remove 8 screws on lower half of frame.
• Pull frame away from screen to remove it, held in place by clips.

If screen does not come loose, use a plastic pick or spudger to release the frame.

Disconnect the battery.

• Remove the black plastic cover from the daughter board.
• (Optional) On the left side, either carefully pry loose and remove the small adjacent board or disconnect its cable.

Disconnect the two cables: the left one for the Display and the right connecting the mainboard and daughter board.

• Remove the mainboard screw.
• The camera can remain connected to the mainboard; it is removable as a single unit.
• Disconnect the right cable from the daughter board below.

Use a heat gun to heat up the front of the display.

• Insert a thin tool between the glass and the frame to create a small gap.
• Work around the edge of the glass using a plastic tool to separate the display from the frame.

The LCD is also glued, making it difficult to remove without breaking; for this guide, replacement was conducted.

• Remove any excess adhesive from the frame once the screen has been removed.
• Insert the display cable through the hole and connect it to the mainboard.
• Test the connection before gluing the display to the frame.

To reassemble, follow these steps in reverse order.
