After a blackout, I can't get my Helios4 board to start.

[Nova]

Hello, I am experiencing a critical issue with my Helios4 board from Kovol after a recent power outage. When I power on the device, the fans start spinning, but none of the LEDs illuminate at all. This includes the power LED and any activity LEDs.

 

Anybody can help me?.

 

I thought it might be the power supply, but I can't find where I could buy it. Does anyone know where to find it?

Thank you very much.

My board have a UART1 (via onboard Micro-USB converter) and dont connect...... with $ sudo picocom -b 115200 /dev/ttyUSB0

 

@Werner Can you think of any other option? Thanks for answering and for your time.
