About the LG 32LK311-TB
The LG 32LK311-TB is a 32-inch CCFL-backlit LCD TV from LG's older LCD range — one of the last generations using fluorescent tube backlights before LED backlighting became standard. These TVs are now 12+ years old and inverter board failures are common as capacitors in the high-voltage inverter circuit age.

FAQ
Q: How do I tell if my LG TV has a CCFL or LED backlight?
CCFL LCD TVs (older models, pre-2012) are thicker and heavier with visible inverter boards. LED LCD TVs are thinner with no inverter board — just an LED driver circuit. The 32LK311-TB is CCFL.
Q: Can I replace CCFL backlights with LEDs?
Technically yes but requires LED strip kits plus CCFL inverter bypass — complex modification. Replacing the inverter board is the simpler repair option.
