Skyworth TV LED Driver & Inverter Boards
The LED Driver Board and Inverter Board are responsible for powering the backlight system inside a television. Without a functioning backlight system, the display panel cannot produce a visible image even when audio and motherboard functions are working normally.
Skyworth televisions use different backlight technologies depending on model generation. Modern Skyworth LED TVs typically use LED Driver Boards, while older LCD televisions may use CCFL Inverter Boards.
