Product Description

Restore the professional picture quality of your television with the LG 49-Inch LED Backlight Strip Set. This comprehensive 8-piece kit is designed as a direct replacement for 49" LG models, featuring a unique "4+4" pair configuration that creates 4 full-length rows of 8 LEDs each. These strips are the primary light source for the LCD panel; when they fail, the TV often exhibits "sound but no picture" symptoms or uneven dark areas. At Robogears, we ensure these replacement strips are built on a premium aluminium substrate to provide superior heat management, significantly extending the life of the LEDs compared to standard plastic alternatives.

Detailed Key Features

  • Exact LG Model Compatibility: Engineered to match original LG factory specifications, ensuring perfect alignment with the internal light guide and diffusers.

  • Aluminium Thermal Base: Features a high-quality aluminium core that effectively draws heat away from the LED chips, preventing "blue tint" and burnout.

  • Complete Array Set: Includes all 8 segments (4 pairs) required to replace the entire backlight system, maintaining uniform brightness across the 49-inch screen.

  • Precision Diffuser Lenses: Each LED is equipped with an original-style optical lens that ensures light is distributed evenly, eliminating bright spots or halo effects.

  • Segmented Design: The 4+4 design allows for secure shipping and precise installation within the original TV chassis layout.

All Technical Details

  • Substrate Material: Aluminum (Al) base for industrial-grade heat dissipation.

  • LED Intensity: Calibrated high-brightness LEDs for vivid picture reproduction.

  • Connector Type: Standard 2-pin interlocking connectors for a stable electrical connection between segments and the main power loom.

  • Colour Balance: Pre-calibrated to match the original LG factory cool-white balance for natural colour rendering.

  • Installation Profile: Slim-line design that fits perfectly within the TV's internal reflective sheets and optical stack.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Diagnosis Tip: If your LG TV screen flashes the logo for a split second and then turns black while the standby light remains on, it is a clear indication that one or more backlight LEDs have failed.

  • Replacement Rule: Always replace the entire set of 8 pieces. Older LEDs will have a different forward voltage than new ones; mixing them will cause current spikes that can burn out your new strips prematurely.

  • Thermal Preparation: Before mounting the new strips at your Pimpri service centre, clean the metallic chassis of the TV with isopropyl alcohol. Use high-quality thermal double-sided tape to ensure the aluminium strip makes perfect contact for cooling.

  • Safety Warning: TV repair involves high-voltage components and extremely fragile LCD glass. Handle the panel with suction cups if possible, and always wait at least 30 minutes for capacitors to discharge before opening the unit.

Package Includes

  • 4 x A-Type Backlight Strip Segments

  • 4 x B-Type Backlight Strip Segments (Forms 4 complete rows of 8 LEDs each)
