Xbox 360 Slim doesn’t power on, not event led lights. Just beeps

Xbox 360 beeps but it doesn’t turn on not even led lights.

It had a dead HDD inside.

I tried to turn it on using my working power supply but I can’t get it to work, it just beeps when i try to turn it on, even eject button does nothing when I push it.

power supply led doesn’t change to green or red, just orange.

Not event a sight of life in console led. It just beeps each time.

So, I decided to open it up to take a look and found this sort of RGH installation. And replaced it all with a new wires, solder and a resistance, same results.

Tried to read the NAND with picoflasher but it doesn’t recognize it, like it were disconnected from the Power adapter.

I suspect something its shorted out?? Anyone can give a hand
