Samsung un55HU6830 next-Generation 6 series, UHD 4k TV, I have a question about the LED connectors to the backlight LEDs.
What are IF1 and IF2 used for? Are those fuses? I tested the results are shorted.
With LED tester, the tested results the group 1 2 3 are...
1+ 1- group leds are 71.4v / 2.7v = 26.4 leds
2+ 2- group leds are 70.4v / 2.7v = 26.1 leds
3+ 3- group leds are 107.4v / 2.7v. = 39.77 leds
Total leds estimated calculation is tv has 92.27leds. Reality is TV has 91 LEDs.
Pic 3. LED driver output 353V, 450 mA, is that means each led is 450mA?
