Replaced screen on Surface Pro 4, digitizer works but screen doesnt!
I replaced the cracked screen on the Surface Pro 4. Although the screen was shattered, the screen still worked perfect previously. I removed the screen and bought a screen replacement. I did the screen switch following many instructions online, but the screen didn't turn on. I thought maybe the replacement screen was defective or the flex ribbon cable might be bad, or something, I got a new Flex screen cable and I got an additional new screen. Replaced both and the screen still doesn't turn on. The computer is still working perfectly (I connected it via HDMI out to a big screen), the Wifi & bluetooth antenna is still working, the digitizer works (i can select things with my hands), but the screen doesn't turn on at all.
TLDR: Screen replacement attempted. Computer works, digitizer works, replaced 2 different screen and one Flex ribbon display cable and screen doesn't turn on.
