Re: A1278 MBP 820-3115-B No backlight (help needed)

Hey!
I've got a similar issue here, but it stays on a black screen with only the backlight on after the startup chime. Nothing else.
I'm new to MacBook repair, but I've watched heaps of Louis Rossman videos.
How did you figure out that it was the SMC?

Re: MacBook Pro black screen with backlight

Okay, very old thread here but I thought I'd comment anyway.
I just got a mid 2012 MacBook Pro for free, but only the backlight works, just a black screen after the startup chime.
I can't see any broken capacitors, and the board is in mint condition, with maybe a slight bit of corrosion on the touchpad connector on the motherboard but I don't see that as having any effect on the display.
Let me know if you see this.
Kind Regards,
Sunny

Hey!
My name is Sunny, a young and keen computer tinkerer, with a YouTube channel on the side where I make tutorial videos and show computer mods that I've completed.
Recently started my own phone repair gig as a way to earn an income, and I'm now diving down what seems to be a rabbit hole which is of course.... learning how to repair MacBooks.
I'm here mainly for schematics, and possibly some tips for when I get stuck in a project. Never been on a forum before, and here seems like the best place to start...
