Bakım ve Kullanım

Proper handling of the screen assembly is vital to prevent damage.

• Always handle the screen by its edges to avoid touching the display surface or damaging internal components.
• Be extremely careful with the flex cables. As noted, bending them excessively (over 90 degrees) can cause permanent damage, leading to a black display or other malfunctions.
• Keep the screen free from dust and debris during installation.

Sorun giderme

Kurulumdan sonra sorunlarla karşılaşırsanız, aşağıdaki yaygın sorunları ve çözümlerini göz önünde bulundurun:

• Siyah Ekran:

  This is often caused by an over-bent LCD cable or a loose connection. Power off the device, recheck the flex cable connection to the motherboard, ensuring it is seated correctly and not bent sharply.

• Touch Not Responding or Ghost Touches:

  Ensure the digitizer flex cable is securely connected. Sometimes, a factory reset (after backing up data) can resolve software-related touch issues, but if it's a hardware problem, the connection or the screen itself may be faulty.

• Lines or Discoloration on Display:

  This can indicate a damaged LCD flex cable, a faulty screen, or an issue with the motherboard connection. Recheck connections. If the issue persists, the screen may be defective.

If troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a professional repair technician or contact the product seller for support.
