Remove display tape from the hinge connector. Treat connector and tape contacts with the contact cleaning spray an brush off all corrosion. Clean both sides of tape.

Capacitors with cross on their top will rise and leak like volcano. Ones without the cuts can leak on the PCB or corrode from their sides.

Any capacitors with signs of corrosion or bulges need to be replaced as they will destabilize the display gradually and can cause shorts and irreparable damage.
