First of all, welcome to the forum!

Did you disconnect the battery, before touching J8500 connector?
Disconnect internal LCD and check for image on external monitor.

Caps Lock light reacts, when press the key?
Tested external video?

Just in case, try DFU with internal LCD disconnected.

Glad to hear the problem was fixed.
And thanks for solution feedback; other people may find it useful.

No idea why MacBooks get some weird issues.
Just know Apple made garbage since 2016...
