Important fitment check:
The broader product-content source also mentions family references such as
55LN5400, 55LN5200, 55LN5700,
55LN6200, 55LN5600 and 55LA6205.
Those broader references are useful for search and identification, but the complete exact fitment list below
comes only from the dedicated compatibility file.
Compare the original NC550DUN-SAAP1,

“Not specified” means no version was supplied in the compatibility file;
it does not mean every production version is confirmed compatible.

Source-reference note:
The supplemental parameter file contains several shortened visible-number strings,
while the broader product-content source separately provides fuller POLA2.0 board references.
They are retained above as source-specific references rather than silently merged or corrected.
Match the original A/B strip profile, 1142 mm length, 12-LED arrangement,
connector, mounting positions, TV model and version before ordering.
NC550DUN-SAAP1 LED Backlight Strips Product Video
View the supplied GuuYebe product video to compare this 14-strip A+B set with the original backlights. Check the printed POLA2.0 references, 1142 mm A+B length, 12-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 production version.
NC550DUN-SAAP1 LED Backlight Strip Details
LED Beads and Optical Lenses
The supplied product information lists 12 LED beads per strip at 3 V per LED. Compare LED count, lens spacing and strip profile with the original backlight assembly.
Connector Interface
Compare the original power connector shape, contact arrangement and orientation before installation. A similar-looking connector or model family alone is not sufficient to confirm electrical and mechanical compatibility.
A+B Layout and Mounting
Check the A/B strip orientation, mounting-hole positions, connector placement and complete physical layout against the original backlight set before installation.
LG TV Has Sound but No Picture? Check the Backlight
If a compatible LG 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.

This is a general GuuYebe LED backlight replacement walkthrough. It is not a model-specific NC550DUN-SAAP1, 55LN5200, 55LN5400, 55LN5700 or 55LA6205 installation video. TV disassembly involves fragile display panels and electrical hazards. Disconnect power and use appropriate repair procedures.
