MacBook won't turn on even after battery replacement

Hey,
I recently tried to power my older MacBook Pro mid 2019 (4 TB ports + TouchBar) after not using it for several months (about half year). First, it powered on after plugging it into power and booted into MacOS even though it showed 0% battery. I let it keep charging for several hours and when I came back and tried to wake it up it did not react. Since then, it won't power on, despite trying SMC and PRAM resets and everything as described by the apple support website.
My guess was the battery which might suffer from deep discharge and needs replacement (even though the laptop is from 2019 it was heavily used throughout the years and battery had over 1k cycles). So I ordered a replacement kit from iFixit and replaced the battery. Everything went fine during replacement. But still, even with the new battery the MacBook won't start.
Is there any chance that it's not the logic board, but instead any software issue? What are your guesses, any recommendations on what else to try?
Cheers
