Re: MacBook A1989 820-00850-A
Its fixed! It wasn't a hardware issue after all.
I was able to get another Mac with usb-c and restore mine using DFU mode and Apple Configurator 2 on the working mac
This guide is very helpful on how to enter DFU and how to restore:

MacBook A1989 820-00850-A
Hi all,
I've got a Macbook 2018 with touchbar that doesn't seem to be powering on. Doesn't have liquid damage or visible damage.
- takes 20.2V and 0.4-0.5A
- lcd doesnt appear to be turning on
- no backlight, no keyboard light, no touchbar
I got the schematic, and started to measure voltage on some components.
Some clues where to start looking would be most welcome
Any help is welcome
