Netgear ac1750 / R6400v2 the power LED will flash red once

Hello, I got a netgear AC1750 / R6400v2 router from a friend that was only behind him. After trying to start, I noticed that there was no reaction except the power LED blinking red (only once, about a second, then it goes out completely). This happens when the power supply is connected to the socket, the router is on "on" and then I connect the router. Otherwise, the LED will not even flash. The motherboard does not look burnt and the harnesses look fine. The power supply is checked and in addition the router on another power supply behaves the same. What could be the reason? Is there a chance to fix it?

Have you tried a simple factory reset?
Push and hold reset for 7-15 seconds while its powered on?
