i have a 820-00875 and fixed the backlight chip, because it had some damage around there and also tested Fuse, correct output on both sides,
plugged it all in and it worked, put it all back together and when i type in the password to log in it starts to load and then the screen goes black, but it looks like the computer puts it self to sleep
because the trackpad stops clicking as well, and i press the power button and it starts and starts loading again, i did look at the lcd sleep sensor on the board but there is no damage at all around there

any ideas where to start :(

thank you guys!

Do NOT look, measure lid signals.
Did you try known good OSX (USB)?

Also check if works if disconnect TP/KB.
