4.1 안전 예방 조치

• Always unplug the TV from the power outlet before starting.
• 전원 플러그를 뽑은 후 전원 버튼을 몇 초간 눌러 잔류 전력을 방전시키십시오.
• 민감한 전자 부품의 손상을 방지하려면 정전기 방지 장갑을 착용하세요.
• Work in a clean, well-lit, and spacious area.
• Handle the TV panel and internal components with extreme care to avoid breakage or damage.

4.2 단계별 설치

1. TV 준비: 화면을 보호하기 위해 TV를 부드럽고 깨끗한 표면에 화면이 아래로 향하게 놓으십시오.
2. 뒷면 커버 제거: Carefully unscrew and remove the TV's back cover. Keep track of all screws.
3. 케이블 분리: Disconnect all cables connected to the main board, power supply board, and T-con board.
4. Remove Bezel and Frame: Carefully remove the TV bezel and any internal frames that secure the LCD panel.
5. LCD 패널을 제거하세요: With extreme caution, lift and remove the LCD panel. It is highly recommended to have another person assist with this step to prevent damage. Place the LCD panel face down on a separate, safe, soft surface.
6. Access Diffuser Layers: Remove the diffuser sheets and reflective layers to expose the old LED backlight strips.
7. 기존 스트립을 제거하세요: Disconnect the power connectors from the old LED strips. Carefully peel off or unscrew the old strips from the TV chassis.
8. 새 스트립을 설치하세요: Align the new LED backlight strips in their designated positions. Ensure the polarity (+/-) matches the connectors. Secure them using adhesive backing or screws, depending on the TV model.

5. 운영

Once correctly installed, the LED backlight strips operate automatically as an integral part of your television's display system. They will illuminate when the TV is powered on and provide the necessary backlighting for the LCD panel. No separate controls or adjustments are required for the backlight strips themselves.

6. 관리 및 유지 보수

These LED backlight strips are designed for long-term, maintenance-free operation once installed. However, proper care during and after installation can prolong the life of your TV components:

• 먼지 방지: Ensure the TV's internal components are free of dust before reassembly. Dust can hinder heat dissipation and potentially shorten component lifespan.
• 신체적 스트레스를 피하십시오: Do not bend or apply excessive force to the LED strips during installation or handling.
• 온도 조절: Operate your TV in a well-ventilated area to prevent overheating, which can degrade LED performance over time.

7. 문제 해결

새 LED 백라이트 스트립을 설치한 후 문제가 발생하면 다음 사항을 고려하십시오.

• 백라이트 없음 / 화면 밝기 조절 안 됨:
  • Check all power connections to the LED strips and the power supply board. Ensure they are securely seated.
  • Verify that the polarity (+/-) of the LED strip connectors is correct.
  • Confirm that all 12 strips are properly installed and connected. A single faulty connection can prevent the entire backlight system from working.
  • TV의 전원 공급 보드가 제대로 작동하는지 확인하십시오.
• Uneven Backlight / Bright Spots:
  • Check the placement of the diffuser sheets and reflective layers. Ensure they are clean, free of dust, and correctly aligned.
  • Verify that the LED strips are flat and securely attached to the chassis, without any gaps or unevenness.
• 깜박이는 백라이트:
  • This could indicate a loose connection or a faulty power supply to the LED strips. Recheck connections.
  • Ensure the TV's power supply is stable.

문제 해결 단계를 수행해도 문제가 해결되지 않으면 전문적인 수리 서비스가 필요할 수 있습니다.

8. 사용자 팁

• 호환성 확인: Always double-check the model numbers on your existing backlight strips against the product specifications before purchase to ensure full compatibility.
• 부드러운 취급: The LED strips are delicate. Avoid touching the LED lenses directly and handle the strips by their edges.
• 나사 정리: During disassembly, use a magnetic mat or labeled containers to keep track of different types and sizes of screws.
