Compare the 4C-LB5504-YH / 4C-LB5505-YH references, A/B lengths, LED count, connector orientation, and mounting positions with the original parts.

Confirm the strip revision: The supplied materials also show alternative visible markings and revisions. These are identification references, not proof that all variants are interchangeable. The Amazon product description says A = 5 LEDs and B = 4 LEDs, while some board-marking strings contain A_4S1P and B_5S1P. Match the physical A/B strips and original part numbers rather than relying on the A/B letters in a printed code alone.

TCL 55S401 / 55S403 / 55S405 LED Backlight Strips Unboxing Video
Watch the GuuYebe product video to see the replacement LED backlight set before ordering. The package is listed as eight strips (four A-type and four B-type). Use the video together with the photos and measurements to check the strip arrangement and physical details against your TV.
This video is a product visual reference; it does not independently verify fitment for any particular TV version.
LED Backlight Strip Details
LED Beads and Optical Lenses
The supplied listing specifies 6 V LED beads and an A/B arrangement of five and four beads. Compare each strip's LEDs, lens positions, and spacing with the removed parts.
Connector Interface
Inspect connector type, orientation, and contact arrangement before installation. Similar-looking connectors do not guarantee that two strips are electrically or mechanically interchangeable.
Backing and Mounting
The source describes an aluminum backing for attachment and heat transfer. Compare mounting-hole locations and strip profiles with the original assembly; protect the TV panel during service.
TCL TV Has Sound but No Picture? Check the Backlight
If your TCL TV plays sound but the screen is black, a backlight fault is one possible cause. With the TV on, shine a flashlight at an angle onto the display and check for a faint image. Seeing an image can suggest a missing backlight while the LCD still produces a picture. This test does not prove that the strips are defective; the LED driver and other electronics may also require diagnosis.
