my screen was broken backlight worked fine ,but now i changed it with a matching one and there is no back light
its a 2015 MJLQ2LL/A
original screen board number is LP154WT2(SJ)(A1)
is there a way to change sth(diode or fuse solder sth) in the screen board to make it work again
Is this a good question?
