Macbook Pro A2779 820-02841 No Power

The board is clean, no signs of water.

When I connect the power supply, L5230 immediately heats up to 40 degrees. I will also upload the picture.

The ammeter shows 20V and 3A. When I press the power button, it restarts itself

Will it be clear if I desolder the SSD storage?

NO.
CPU has its boot partition on SSD.

Does that mean the device is beyond repair?

What is the charger behavior without battery connected?

Без батареи все почти так же. Сначала он ненадолго показывает 5 В и 0,12 А, затем переключается на 20 В и 0,15 А. Через 5 секунд он перезапускается, затем остается на 20 В и 0,00 А, и больше ничего не происходит. Когда я нажимаю кнопку питания, весь процесс начинается заново.

Test the board alone on the desk.

Actually, only the USB port and the power button were connected, but I still removed it from the case and tried it that way as well. Nothing changed, everything stayed the same.
