LED TV backlight strips Features:

Perfect OEM Fit

The left and right light strips are precisely sized at 488 mm and 358 mm to match the original backlight layout used in 43-inch models such as the Arcelik 43VLX7730SP. The connectors align exactly with the factory driver board, making installation simple and worry-free—no rewiring and no compatibility issues. With eight strips included, the entire panel is fully covered for consistent illumination across the screen.

Clean, Even Illumination

Built with a 3+4 LED configuration running at 3V, these strips provide bright, uniform lighting with an efficiency of up to 230 lm/W. The 1313FC LEDs offer a wide 120° beam angle and a flicker rate above 3200 Hz, delivering smooth, stable brightness. This helps reduce hot spots and dim patches, resulting in clearer detail and more comfortable long-term viewing.

Copper Cooling Design

A pure copper substrate with high thermal conductivity (380 W/m·K) keeps operating temperatures below 52°C. This prevents early brightness degradation and meets UL 94V-0 safety standards. The LEDs feature reinforced packaging with a 3.8 N pull strength for better durability and resistance to wear over time.

Stable, Consistent Output

Premium 1313FC LEDs maintain tight wavelength control and stable brightness from batch to batch. A 7S1P circuit layout ensures reliable power delivery, and each production run is fully calibrated and tested for optical performance. The result is dependable, OEM-grade image quality after installation.

Safe and Reliable

The strips are RoHS-compliant and backed by a one-year warranty with 24-hour customer support. Suitable for both home and commercial environments, they provide a long-lasting and dependable solution for common 43-inch backlight failures.

LED TV Backlight strips FAQ：

Q: Are your backlight strips suitable for curved TVs? A: Some of our backlight strips are designed to be flexible and can be adapted for curved TVs. However, it depends on the degree of curvature and the specific requirements of your TV model. Provide us with the details of your curved TV, including the brand, model, and curvature radius. We'll be able to determine if our standard strips can be used or if a customized solution is needed.

Q: What if I need to install the backlight strip in a high - altitude area? A: High - altitude environments may have different atmospheric conditions that could potentially affect the backlight strip. The main concern is the reduced air density, which can impact heat dissipation. Our standard backlight strips are designed to operate within normal environmental conditions. For high - altitude installations, we recommend consulting our technical team. They can suggest any necessary modifications or alternative products to ensure optimal performance.

Q: Can I control the brightness of the backlight strip? A: Many of our backlight strips come with the option to control brightness. Some models are compatible with external dimmer switches, while others can be adjusted through the TV's built - in settings if it supports backlight brightness control. Check the product description for your specific backlight strip to see what brightness - control options are available.

Q: How do I clean the backlight strip without damaging it? A: To clean the backlight strip, first, turn off the power and unplug the TV. Use a soft, dry cloth to gently wipe the surface of the strip. Avoid using any abrasive materials or cleaning agents as they can scratch the strip or damage the LEDs. If there are stubborn stains, slightly dampen the cloth with water, wring it out thoroughly, and then wipe the strip. Make sure the strip is completely dry before powering on the TV again.

Q: Do you provide installation services for the backlight strip? A: We do not directly provide on - site installation services. However, we can recommend a network of professional installers in your area if available. Additionally, we offer comprehensive installation guides and support to assist you if you choose to install the backlight strip yourself. Our customer service team is also on standby to answer any installation - related questions.

Q: What is the impact of voltage fluctuations on the backlight strip? A: Voltage fluctuations can be harmful to the backlight strip. Frequent or significant voltage spikes or drops can cause the LEDs to burn out prematurely, affect the color accuracy, or lead to flickering. To protect the backlight strip, it is advisable to use a voltage regulator or a surge protector, especially in areas with unstable power supply. This will help maintain a stable voltage and extend the lifespan of the backlight strip.
