Source-reference note:
The supplied parameter file labels the manufacturer part number as
Vizio LB55120, while the dedicated compatibility file identifies
Insignia NS-55DR620NA18 as the exact TV fitment.
These source-specific references are retained separately rather than silently reconciled.
Match the original LB55120 / LB55072 / GJ-2K16 markings,
1118 mm A+B length, 7-LED layout, connector and mounting positions before ordering.
LB55120 LED Backlight Strips Product Video
View the supplied GuuYebe product video to compare this 14-strip set with the original backlights. Check the LB55120 / LB55072 / GJ-2K16-550-D714-V4-L / GJ-2K16-550-D714-V4-R references, 1118 mm A+B length, 7-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.
LB55120 LED Backlight Strip Details
LED Beads and Optical Lenses
The supplied product information lists 7 LED beads per strip at 3 V per LED. Compare the LED count, lens spacing and A/B strip profile with the original assembly.
Connector Interface
Compare the original connector shape, contact arrangement and orientation before installation. A similar-looking plug alone is not sufficient to confirm electrical and mechanical compatibility.
Mounting and Fitment Check
Compare the mounting-hole positions, connector placement, 1118 mm A+B dimensions and complete physical layout with the original set before installation.
Insignia TV Has Sound but No Picture? Check the Backlight
If a compatible Insignia 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.
