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

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?
