Sente Backer#250 here..I keep hearing about this Rev2 mainboard replacement? I am dealing with this very same symptom (no display and no LEDs) after a windows update and shutdown of the Mini PC. I turned it on again and I hear it spinning although much louder than then usual whisper quiet mini pc noise, and I see the network port lit up green, the polycade backlit keys are lit up and the mouse is powered on too. But no DISPLAY on Monitor, and the jubilant LED lights are off permanently. Has anyone here been reached out to by Polycade support ? I have not used the Sente much since I got it in late 2024. Has anyone figured out what is going on with this particular issue ?
