2 Display Backlight not working after replacement.
So I replaced the display assembly (thanks for the great tutorial), and it worked fine for 2 days but it suddenly stopped working, after some debugging I noticed that if I shine a light behind the Apple logo the screen can be seen correctly and if I connect and external monitor it works great. I've read it my be a fuse, cable or conector but I'm not sure how to test them. My board is 820-3787-06.
Thanks
Es esta una buena pregunta?

FWIW the old screen worked before (it had damage) I connected it right now and it has the backlight problem too.

Tried a PRAM reset? If not, then could be a blown backlight fuse any history liquid damage drop damage? If you need board level repair, I can always help you out peep bio for that, but first thing is to try a PRAM reset.

I've done PRAM and SMC reset it didn't help. It was liquid damage

Sounds like a board problem then. Unless you have a bad screen, but if the old one is doing it, then I'd go backlight problem
