Default Flashing Baclight UN60Fh6003 - PFC off

Help is appreciated as always. I have Samsung UN60FH6003 with power supply BN44-00669A. When you plug it in, the backlight is flashing at roughly 1 Hz. Heat spots on the board, i thought diodes for sure. But when i measure the filter caps voltage, its 162v -pfc is off. This is the cas with or without the main board connected to power supply. LED Diodes checkout. Backlights checkout. Caps at the LED Driver checkout. Thoughts?
