hi everybody, I could sure use some help on this one. when I turn this tv on the power supply turns on, PFC puts out roughly 400 volts on the two main caps, cp806 and cp807. I sampled the voltage at the led header connector, when the power first came on I got a little over 300 volts on both sets of gray and black wires. Im assuming two circuits and the led array would be split in half, top half and bottom half four equal led strips each circuit. that would explain the voltages being the same for both circuits... Before I pull the lcd panel and inspect the leds and wiring I would like to know what the voltages should be?
After the power supply warmed up a little the voltages both dropped to around 246volts. I tested from chassis ground and the gray wires and its the same from the gray wires to the black wires both sets are the same.
Power Supply #BN44-00776A
