Source-reference note:
The supplied product-content source lists
LC500DUE-SFR2 as the part number and gives
AGF78180301 / AGF78240901 / AGF78401201
as manufacturer part numbers.
The source panel-number string repeats LC500DUE-SFU3 and
LC500DUE-SFU4; the parameter table above displays each unique panel identifier once
for readability without changing the supplied reference family.
The separate parameter file also includes 6637L-002 in addition to
6637L-0021A. Both source references are preserved.
LC500DUE-SFR2 LED Backlight Strips Product Video
View the supplied GuuYebe product video to compare this 12-strip set with the original backlights. Check the LC500DUE panel references, 6637L / 6916L markings, 998 mm L1+R1 / L2+R2 dimensions, 10-LED layout, connectors and mounting positions before ordering or installation.
The product video is a visual reference for the supplied strip set and does not by itself confirm compatibility with every TV production version.
LC500DUE-SFR2 LED Backlight Strip Details
LED Beads and Optical Lenses
The supplied product information lists 10 LED beads per strip at 3 V per LED. Compare the LED count, lens spacing and L1/R1/L2/R2 strip profile with the original assembly.
Connector Interface
Compare the original power connector shape, contact arrangement and orientation before installation. A matching TV model family alone is not sufficient to confirm the installed backlight assembly.
Mounting and Fitment Check
Compare the mounting-hole positions, connector placement, 998 mm L+R dimensions and complete physical layout with the original set before installation.
TV Has Sound but No Picture? Check the Backlight
If a compatible TV has sound but the screen remains dark, failed LED backlights are one possible cause. Shining a flashlight at an angle across the powered screen may reveal a faint image, which can indicate that the LCD image is present but the display is not being illuminated normally. This test does not prove the LED strips are faulty; the LED driver, power supply or other circuitry may also require diagnosis.

TV LED Backlight Strip Replacement Process Video
This is a general GuuYebe LED backlight replacement walkthrough. It is not a model-specific LC500DUE-SFR2, 50LN5400-UA, 50LN5700-UH, TX-L50B6B, 50L4300U or E500I-A0 installation video. TV disassembly involves fragile display panels and electrical hazards. Disconnect power and use appropriate repair procedures.
