uArm disconnects when connecting power

uArm Serial No.: UARM-05051707BA
Firmware Version: 3.2.0
Operation System: Mac
uArm Controlling Method: uArm Studio

Hello all,
My uArm Swift Pro V1 stopped working. The LED is red when connecting power and USB. No beep.
As soon es i am unplugging power the LED turns green and it beeps. It connects to uArm Studio. But it doesn’t move since there’s no power.
When i plug in the power it disconnects and the LED turns red.

Do you have any suggestions? I suppose there’s a fault on the board or the motors.

Update:
I tried another power brick without success.

And i disconnected the motor cables, connections and removed the motor drivers from the board. Same result.

Without the power cord the serial connection is working.
