Carefully lift both the screen and motherboard, to access to the ribbon cable underneath.

Use a heat gun (or hair dryer) to apply low heat to the ribbon cable attachment on the motherboard.

Avoid overheating the ribbon cable and motherboard or they may melt.

Carefully use a nylon spudger to separate the ribbon cable from the motherboard and remove the screen.

This step may require two sets of hands; having a friend always helps!
