When plugged into the socket, the LEDs and the power supply relay blinked, arming and disarming, I isolated the LED bars, it didn't solve the problem, I thought they were leaking and they really were, but it didn't solve it, the defect was in the transformer of the LP801CS power supply, cold soldering. | I fixed it and it started working again.
