Carefully lift and turn over the LCD screen so that you are able to access the motherboard.
Carefully disconnect the LCD screen ribbon cable from its ZIF connector with your thumb and index finger.
When removing the ribbon, it is best to firmly grasp the ribbon cable with your thumb and pointer finger. Pull out the cable as straight as possible. This is the best practice to prevent damage to the ribbon cable.
Be careful to not rip the ribbon wire or the red and black power wires when pulling the LCD screen out.
Use the soldering iron to separate the black and red power wires from the motherboard.
Not knowing where the power wires go could disrupt the power distribution and lead to power outages and damage to the motherboard. The black wire is the negative power wire and the red wire is the positive power wire.
