MBP 2015 Black Screen

[EMENCII]

Hello everyone,

in April I bought a MacBook Pro 2015 on ebay, and it worked fine, until... I have an hackintosh at home, and I used on it a normal usb key, on which I loaded Ubuntu live (just extracting the ISO on it) and inserted in the MBP to start Ubuntu.

What greeted me was Clover (the hackintosh's bootloader), which started MacOS and hung for a while on it. Then I turned off the laptop, to reboot it, and I just got a black screen, nothing more.

The insides of the computer looked fine (I met a friend who brought the pentalobe screwdriver), though I didn't look too closely at it. The computer does charge.

I tried connecting a tv via the HDMI, resetting the SMC (the orange light turned green), resetting the PRAM, logging in, sleeping it and waking it up, safe mode, recovery mode, cmd+f1, booting ubuntu from the usb key, but none of these worked.

Since going to a repair shop is gonna drain me some hundred bucks, I decided to give the DIY solutions a try... Though I don't know where to start.

I guess checking the voltages on the motherboard is also a good thing to do, but even though I watched some videos from Louis Rossmann I'm still a bit uncertain...

Any help would be hugely appreciated, even if you know some other site that could help me or where I could ask for help...

Thank you for your help,

Marco

Ok. 

So your issue is most likely a hardware failiure that is not related to your Hackintosh activities.
What you could do, is remove the SSD and wireless card, and then try to turn it on. That will eliminate those 2 components.
I dontt think the RAM is removable in that model, but i could be wrong. If it is, remove 1 stick and try and switch the 2 sticks

That's what I'm thinking too, but buying antother 400 euros worth of motherboard is not a thing I'd like to do... That's why I want to solve this another way...

The RAM cannot be removed. I am waiting for ebay to ship the screwdriver so that I can open it again. Though I'm not sure it will turn on without them, I heard it needs EVERYTHING to be there and working in order to start, not like a PC. It sounds unlikely to me, but who knows what apple did...

Nah. It should boot with no wifi card or SSD.But the most likely scenario is a dead Logic board
