The problem with the original Xbox one consoles that had a problem like that was the main filter capacitor in the power supply brick. I have replaced many of those to successfully repair the problem. On the One S consoles it is either the main filter capacitor in the power supply box inside the unit or the three filter caps on the main board right where the power supply box connects to the motherboard. Simple fixes for anyone with some soldering experience.
