So i bought a new lcd screen for my dell inspiron 15 7559 (my older one had dead pixleeel in one corner) and plugged it in first when i started the pc the screen worked fine but then i had to unplug it again to get the top cover from the laptop and when i tested it again it had no backlight. I tried the oldee one and at first the older one worked fine but when i tried to fix the new one the older one had no backlight too. So i dont think that the cable is brokem because the older one workes fine in the beginning. So i dont know if the backlight ia turned off from Windows because i c n plug in an external screen and this one works.

Thank you for helping.
