   Pay close attention to the issue of static electricity. Before attempting any repair, ensure you ground yourself with an ESD (Electrostatic Discharge) strap. This prevents static electricity from damaging the electronic components within the phone.

3. Kablo Kullanımı: Ensure the LCD cable is not over-bent. Bending the cable beyond 90 degrees can cause a black display or permanent damage to the screen.
