LG 50LF5800 Reference
The exact compatibility source includes 50LF5800 and 50LF5800-ZA. Compare the panel label, connector, A/B strip layout and mounting positions before ordering.
LG 50LB580V Reference

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.

TV disassembly involves fragile display panels and electrical hazards. Disconnect power and use appropriate repair procedures.
