MacBook Pro 2015: Blank screen after screen replacement?

I've just replaced the screen on a macbook pro 2015, with a second hand screen.

You can hear the device booting up but there is no display. Unfortunately I followed a youtube video that never mentioned disconnected the battery - wish I'd done more research so I'm worried components are fried. The macbook was powered off.

Is there a way to know if the screen is functioning as it was second hand?

I was considering attaching the old broken screen to see if it still displays incase I've fried some components.

Thought I would ask here before I done anything else, really appreciate some advice on what to do next.

Use a flashlight shining it though the Apple Logo, do you see the faint image of your desktop and its icons?

If you do then the backlight power circuit needs repairs.

Yeah that's what has happened, what I get for blindly following youtube. I'm not up to soldering on small circuits. Do you know how much I'm looking at to fix? Thanks for you reply.

@scott kerr - It all depends! It could be as simple as a blown fuse, or it could be much deeper!

Try to find an independent repair shop who has Mac experience and micro-soldering skills locally.

Can you tell us where you live maybe we can aim you to someone. Country and nearest major city.
