Product Description

Restore the professional picture quality and vividness of your television with the LG 49-Inch LED Backlight Strip Set. This complete 8-piece array is specifically engineered for 49" LG LED TV models, utilising a unique "5+4" segment configuration to create 4 full-length horizontal rows of 9 LEDs each. These strips serve as the primary illumination source for your LCD panel. At Robogears, we prioritise long-term reliability; therefore, these strips are constructed on a high-grade aluminium substrate. This aluminium base provides vastly superior heat dissipation compared to standard PCB strips, effectively preventing LED burnout and the common "blue screen" effect caused by overheating.

Detailed Key Features

  • Perfect LG Compatibility: Designed to match original factory optical specifications, ensuring flawless light distribution and alignment with the TV's internal reflective sheets.

  • Aluminium Thermal Core: The metal substrate draws heat away from the LED chips rapidly, ensuring stable performance and a significantly extended service life.

  • Full Array Replacement: Includes all 4 pairs (8 total pieces) needed to replace the entire backlight system, maintaining uniform brightness across the 49-inch display.

  • Precision Diffuser Lenses: Each LED is fitted with a circular optical lens that ensures light is spread evenly across the LCD, eliminating "bright spots" or shadowing.

  • Segmented Design for Safety: The interlocking A and B segment design allows for easier handling during installation and more secure shipping.

All Technical Details

  • Total LED Count: 36 High-intensity LEDs across the complete 4-row set.

  • Substrate Type: Heat-resistant aluminium for industrial-grade durability.

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

  • Connector Interface: Standard 2-pin interlocking connectors for a reliable and stable electrical connection.

  • Mounting Profile: Slim design that integrates perfectly into the original TV chassis and optical stack.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Diagnosis Tip: If your LG TV has sound and responds to the remote, but the screen is dark (or flashes the logo briefly before going black), the backlight array has likely failed.

  • The "Full Set" Rule: We strongly recommend replacing the entire set of 8 pieces. Replacing only a single segment can lead to voltage imbalances that cause the remaining old LEDs to fail shortly after the repair.

  • Surface Cleaning: Before installing the new strips at your Pimpri workshop, ensure the metal chassis is perfectly clean of old adhesive residue. Use high-quality thermal double-sided tape to ensure the aluminium strip makes perfect contact with the chassis for maximum cooling.

  • Panel Handling: LCD glass for 49-inch TVs is extremely thin and fragile. We recommend using screen suction cups and working on a soft, dust-free surface to prevent panel cracking or diffuser contamination.

Package Includes

  • 4 x A-Type (5-LED) Backlight Strip Segments

  • 4 x B-Type (4-LED) Backlight Strip Segments (Forms 4 complete rows of 9 LEDs each)
