Hi, Andre. Try a different power supply (brick and cable), these commonly have capacitors fail on them. If the problem persists even with a known-good power supply, the problem is internal. I’ve seen the internal power supply unit itself, the “southbbridge” IC, the APU, and one or more of the MOSFETs and other components on the voltage rail be at fault. Here’s a standby voltage diagram to help you narrow it down to the correct component. Hope this helps, good luck!
