Product Description

Restore the professional-grade brightness and colour accuracy of your display with the LG 42-Inch LED Backlight Strip Set. This complete 8-piece array kit is specifically designed as a direct replacement for 42" LG LED TVs, featuring a specialised "4+4" pair configuration that forms 4 full-length horizontal rows. These strips are the critical light source for the LCD panel; when they fail, it commonly results in the "sound but no picture" symptom. At Robogears, we ensure these strips are manufactured on a premium aluminium substrate. This aluminium base provides significantly better heat dissipation compared to standard PCB strips, preventing the LEDs from overheating and ensuring a much longer service life for your repaired unit.

Detailed Key Features

  • Exact LG Factory Fit: Engineered to match original optical and electrical specifications, ensuring 100% alignment with the internal light guides and diffusers.

  • Aluminium Thermal Core: Built on a high-conductivity aluminium substrate that rapidly draws heat away from the LED beads, preventing "blue tint" and burnout.

  • Complete Array Replacement: Includes all 8 segments (4 A-type and 4 B-type) required to replace the entire backlight system for uniform screen illumination.

  • High-Clarity Optical Lenses: Each LED is capped with an original-style diffuser lens that ensures light is spread evenly across the 42-inch panel, eliminating bright spots.

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

All Technical Details

  • Total LED Count: 32 High-intensity LEDs across the full 4-row set.

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

  • Colour Balance: Calibrated to the original LG factory cool-white point for natural and vibrant colour reproduction.

  • Connector Integrity: Features standard interlocking 2-pin connectors for a secure electrical bond with the TV's internal wiring harness.

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

Prototyping & Engineering Tips (Robogears Exclusive)

  • Diagnosis Tip: If your LG TV screen flashes the logo briefly and then goes black while the audio continues, the backlight driver has likely detected a failed LED and entered protection mode.

  • The "Full Set" Rule: We strongly recommend replacing the entire set of 8 segments. Mixing new segments with aged ones can cause voltage imbalances, leading to the remaining old LEDs failing shortly after the repair.

  • Surface Preparation: Before sticking the new strips into the chassis at your Pimpri service centre, ensure the metal surface is perfectly clean of old residue. Use high-quality thermal double-sided tape to ensure the aluminium strip makes maximum contact for cooling.

  • Panel Handling Safety: 42-inch LCD glass is extremely fragile and susceptible to cracking if flexed. Always use screen suction cups and ensure you have a flat, soft, dust-free surface to rest the panel on during the repair.

Package Includes

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

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