Hi. I got a problem - after I turn on the console, the blue diode lights up and continues to glow. Both screens remain black. I tried to go to the recovery menu, or boot using ntrboot - nothing, the blue diode lights up without stopping. The problem is that if I take a bare motherboard, which is not connected to any cable and connect the battery to it and turn on- the led lights up and does not go out. The motherboard itself looks like new, there are no signs of damage anywhere. What could it be?
