Premium replacement backlight strips for TCL 55 inch TVs

Refresh your TCL television with the PANMILED LED backlight strips designed to replace aging lighting along the screen edge. This four-piece kit is compatible with a range of TCL models, including 55S421, 55S423, 55S425, 55D6, 55F6, 55U3800C, and 55U3900C, helping you restore a more even glow without a full panel replacement. The kit provides two length variants—18.5 inches and 21.38 inches—adding up to roughly 39.9 inches in total when assembled. Each strip contains 15 LED beads (A+B), and the back of every piece wears a double-sided adhesive for quick positioning.

What you get in the box

  • Four LED backlight strips, designed as a straightforward replacement
  • Two length options: 18.5 inches and 21.38 inches
  • Each strip holds 15 beads (A+B) powered at 6 volts
  • Pre-applied double-sided adhesive for secure mounting

Real-world use and what you might notice

When installed correctly, these PANMILED backlight strips can contribute to a more consistent screen brightness along the panel, reducing visible dark areas near the edges and frame. The uniform light helps highlight details in darker scenes and can enhance perceived contrast without replacing the entire backlight assembly. The result is a cleaner, more comfortable viewing experience during movies, sports, and streaming content alike.

Practical installation ideas and tips

  • Check compatibility by comparing the photo references with your TV’s original parts before proceeding.
  • Power off the TV and allow components to discharge before handling any strips.
  • Peel away the protective backing, align the pieces with the frame, and press firmly to activate the adhesive.
  • A quick test after installation can help verify brightness distribution before final mounting.

Support and service

PANMILED backs products with a 180-day after-sales service guarantee. If you have questions during installation or usage, customer service typically replies within 24 hours to help troubleshoot or clarify compatibility.
