I bought this second hand and it was working fine: turned it on, reinstalled the system, restored TimeMachine, charged the battery…
But it was filthy. Used-in-a-barn filthy!
So I opened it up, cleaned everything, reassembled and… nothing happened… it just won't turn on…
I triple-checked all the connectors, tried re-setting the SMC, put some tape unde the battery screw (saw this here on ifixit) and still nothing. No water-based products were used, isopropyl alcohol only!
This is the first 'modern' Macbook I ever worked on. Previously I done up to 2015 only so I am lost in regards to troubleshooting it.
Any help would be appreciated.
Thanks

EDIT: I remembered I did break one thing - the flat cable of one of the fans when I was cleaning it. I did soldered it back and it did got about 2mm shorted and I couldn't test it but I assume if it weren't working that wouldn't be a reason for the computer not to turn on…?
