Plug in and backlights with Smart Tv powered by Tizen logo shows on screen
then nothing, no stby led or response to remote, no sound from hdmi input.
This has only 1 board, a 3in1_kant_su2.
Try a usb stick with update firmware from Samsung and usb stick just flashes a couple of times, recognises usb, but thats it.
Remove ribbon to panel, same results.
I believe the leds are in an array of 3 x 12 @3v/led, going by what led sets are being sold for this tv on ebay and aliexpress.
1 string of 12 leds, power supply in 84v, out 54v, voltage drop 30v
1 string of 24 leds, power supply in 185v, out 84v, voltage drop 100v
which the string of 24 leds doesnt seem right!
Though still not ruling out bad panel or board.
