Hi there, thanks for looking at my thread.
I have an issue with my DELL INSPIRON 15 7559 where there is no back light but there is display.
I've been fiddling around with the unit, turns out there's no fuse for the back light so not a simple fix.
After digging around i found there was no 19 Volt supply to the display but there is 19 volts on other close areas of the board.
LED_EN and LED_PWM on the inverter are receiving their proper 3.3v toggle current so that's not the issue either.
Attached i have some schematics, if anyone has any experience in this please help i'm at a loss here.
Cheers!
