So folks know... I had the issue and disassembled and reassembled. Worked fine for a while and then blacked out again.
Installed the "optional" embedded controller flash update and, boom, lcd restored. Have a flashlight handy and use it pointing down from the top of the screen (not at the screen) so you can see. Test it with a normal screen up to get the hang of it.
Hit "2", enter and then "Y" to flash. System will turn off when done. Power on and lcd is back on.
Easier if it holds...

no time for that, man, and you don't have to open up every component to make it work.
the more you do that, the more you F-it up!
