I have a Samsung LN46A530 46" LCD TV. Lost my backlight and wondering if the two wire connectors feeding the R and L inverters is where I would meter for power, and if not what are these for ? Or is it the ribbon cable on the top left (it's pin ids are 1. 12v_cold, 2.FB, 3.FB, 4.GND, 5.GND, 6.LD, 7.LD). Would this TV use 12 V to power the inverters ??. The inverter enable is on (5V), so I assume it is either the pwr supply or the master inverter.
