Hi Hoping some one could help point me in the right direction. I XBR4 has no error code displaying, It does have a heart beat. It powers on the backlight flickers for a millisecond and then it sits remaining powered on. I have poked around a bit unpluging the backlight inverters from the left side brings up a 6 blink code.... unpluging from the right shows no code. not sure if it means the DF3 board is bad or not.
