How does one know weather it’s the Motherboard or the PSU? What should the PSU be outputting to check it first? Or any other ways to check it

there are a few things that can help diagnose whether it is the power supply or the circuit board but sometimes it can be both. One thing you can do is just knowing the conditions of the home, did you have some power outage, or blinking of lights during storms and things like that. If you don’t have a battery backup sometimes surge protectors are not going to save a system from failure just from power blinking on and off. This can cause backfire like issues that can glitch out the control board or power supply or domino the both. If you see power and the light turns on but when you hit the buttons nothing happens that either means the circuit board is failed because it is unable to process commands, or the power supply is only providing enough power to turn on the circuit board but nothing else. If you can not get a light at all and have tried plugging it in and out over and over and nothing no lights or anything than it is a good bet the power board has failed. If you don’twant to pay repairs take best guess

Very often, espacially if the PSU is som years old, the electrolyt capacitors will dry out.

You can see it when the surface has blown up and is rounded. Normally this capacitors are flat. If you see, that one or more of this capacitors is bended, than replace all with the same values (capacity and voltage).
