Source-reference note:
The supplied Amazon content lists LB55135 as both Part Number and Manufacturer Part Number,
while the separate parameter source lists Insignia LB55135 as Manufacturer Part Number.
Both source-specific forms are retained.
The separate parameter source also contains the literal visible-number entry
LB-DM3030-GJBBY555X9ABG2-R-H LB-DM3030-GJBBY5.
It is preserved exactly as supplied rather than silently completed or corrected.

TV Has Sound but No Picture? Check the Backlight
If a compatible Element or 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.
