Hi,
I have a LG 55 inch LED tv which has no video. I tested the SMPS board and looks like voltage to backlight LED is missing. I could hear the sound and able to change volume and source so concluded that main board is ok. I'm getting around 0.06V when checked against LED + and - terminals. Also able to get 3.2V on DRV on from mainboard. Any idea whats going wrong?
