I just replaced the cracked screen on my Lenovo Thinkpad T460 and now all I get is a black screen. If I plug an external monitor to it I can log into Windows 10. I've tried Hard Resetting it. I've tried going to Lenovo support and downloaded the graphics drivers. I've reseated the RAM. I've reseated the graphics cable pins on both ends and still cannot get a picture. I've returned the old cracked screen as it was previously working and now it does not work either. I've also reset the graphics by Win+CTRL+Shift and B and that didn't work either. The graphics is an Intel HD 520.
What am I missing?
