A2779 820-02841-A black screen but not in recovery

[thomamagic]

Hello, I have a problem with a MacBook Pro A2779 820-02841-A when it starts up the apple logo is displayed and as soon as the session starts the screen goes black.
I've tried a reinstallation, a DFU, unplugged keyboard, trackpad, battery, angle sensor, but nothing changes, no trace of oxidation on the motherboard.
Do you have any ideas?

So you can even complete recovery, but no image after last restart?

Just in case, complete the recovery using external monitor.
Then let see what happens after finish installation.
