Product Description

Restore the professional-grade 4K clarity and vibrant contrast of your television with the Samsung 43-Inch 4K LED Backlight Strip Set. This complete 8-piece replacement kit is specifically engineered for 43" Samsung 4K models, featuring a specialised "7+5" segmented design that combines to form 4 full-length horizontal rows of 12 LEDs each. These strips serve as the primary illumination source for your high-resolution LCD panel. At Robogears, we prioritise long-term reliability; therefore, these strips are constructed on a premium aluminium substrate. This aluminium core provides vastly superior heat dissipation compared to standard plastic or fibreglass strips, effectively preventing LED burnout and common display issues like "dark patches" or "sound but no picture."

Detailed Key Features

4K Panel Optimisation: Specifically calibrated to match original Samsung factory optical specifications for 43-inch 4K series, ensuring uniform brightness and deep contrast.
Aluminium Thermal Core: The high-conductivity metal substrate effectively draws heat away from the LED beads, preventing "blue tint" and ensuring an extended service life.
Complete Array Replacement: Includes all 4 pairs (8 total pieces) required to replace the entire backlight system, maintaining perfect electrical balance and uniform light output.
Precision Optical Lenses: Each LED is fitted with an original-style circular diffuser lens that ensures light is spread evenly across the 43-inch surface, eliminating "bright spots."
Segmented Interlocking Design: The 7+5 pair configuration allows for safer handling and more secure shipping of these high-precision display components.

All Technical Details

Total LED Count: 48 High-intensity LEDs across the complete 4-row array.
Substrate Type: Heat-resistant aluminium for industrial-grade durability.
Colour Balance: Pre-calibrated cool-white spectrum to match original Samsung factory 4K standards for natural colour reproduction.
Connector Integrity: Features high-reliability interlocking connectors for a stable electrical bond with the TV's internal wiring harness.
Mounting Profile: Slim-line design that maintains the structural integrity of the internal reflective sheets.

Prototyping & Engineering Tips (Robogears Exclusive)

Diagnosis Tip: If your Samsung 43-inch 4K TV displays the logo for a split second and then turns black while the sound remains on, the backlight driver has likely detected a failed LED and triggered protection mode.
The "Full Set" Rule: We strongly recommend replacing the entire set of 8 pieces. Mixing new segments with aged ones can cause voltage imbalances that lead to the remaining old strips failing shortly after the repair.
Surface Preparation: Before sticking the new strips down at your Pimpri workshop, thoroughly clean the TV’s metal chassis of old adhesive residue. Use high-quality thermal double-sided tape to ensure maximum cooling contact with the chassis.
Panel Handling Safety: 43-inch LCD glass is extremely thin and fragile. Always use professional screen suction cups and ensure you are working on a soft, dust-free surface to prevent panel cracking or contamination.

Package Includes

4 x A-Type (7-LED) Backlight Strip Segments
4 x B-Type (5-LED) Backlight Strip Segments (Forms 4 complete rows of 12 LEDs each)
