Passo 1 — Electro-Static Discharge (ESD) ¶
Passo 2 — Check the Connection ¶
Check the display connections on the cables and the logic board. Dirt, dust or debris can cause a faulty connection and should be cleaned with a soft brush and high concentration isopropyl alcohol (at least 90%). Inspect the connectors and clean as necessary.
Passo 3 — Damaged IC Connector ¶
The display has an IC that could be damaged. Check particularly on the upper left and right corners. Any signs of damage indicate the part is defective and needs to be replaced with a new one.
