Had a broken screen on my 15 7548. Worked ok, just cracked. Replaced the screen, new screen didnt work. Put the old screen in, now it doesnt work.
Look closer and the screens (both) are working but no backlight. Replaced LCD cable, still no backlight.
Reading up on other folks having backlight issues and i guess there is a fuse that can be blown? I looked around on my board for a fuse, cant find it. Any help locating this tiny thing?
