LG 42LN5300 backlight is not working

My TV's picture won't work. It has sound, inputs work. If you hold a flashlight up to the screen, you can kind of see a ghostly image. I have found online that it is most likely the backlight inverter, however I can't find one on my TV. Could you tell me what backlight inverter board to get for a LG 42LN5300 TV? I can't find any results when I search for it. Is it possibly the main board? Or the power board?
