How to troubleshoot and repair not powering on motherboard complete solution

As you can see we have HP 280 G4 motherboard. Again repeated case again and again, I have made a video on this. So look like I've just put it in. I have connected the power. But still no one is giving any indication here. Neither the standby LED is lit nor is there anything here. And look here,

our power is directly connected to this. So what is the fault in it now? Let me disconnect once and show you. How to do live troubleshooting? In this way, the fault can also occur in your case motherboard. So we have made many videos on this. Still, we do n't have any option right now. So let's make it one more time.

You will see a new case in this. So let's start this. Let's see. So for now, first of all we are going to check with the multimeter after connecting the power to the SMPS that the voltage which our multimeter is showing in the multimeter, here on the ATX power connector at P3, that 12 volt will come here.

We will check this in real time, where is the fault in which area. So you will see that 12 watts are present here. And like I will connect this connector here. You can see the real time voltage. So the voltage here should not drop our. If it drops, it means that there is a

shorting somewhere in this VRM section. So see, as I connected it, the VRM voltage is stable. I have installed the connector here properly. And there's one more connector left. I am going to show you live here. Look, you can see 12 volts here. It is available. Ok? In the multimeter. But this connector also has 12

volts. Ok? As I apply it, it will drop the voltage. You will see the voltage drop. So this means that we will diagnose the shorting in this area here. This is the new way, I told you. I told you in a video and if you know it then you should implement it. If you do
