QNAP TS-451 power issue (on motherboard)
This unit has an external power supply (brick). I believe I have a component issue somewhere on the motherboard. Possibly between the DC input and the power button. The unit will briefly power up then shut down. I hear a soft “click” before it turns off. Customer service was unable to resolve the issue and the board is not an available item. I’ve tried a different (good) power supply with the same result. I bought a new replacement NAS. So, this broken one is ready for the workbench or trash can. Anyone game to trouble shoot?
Is this a good question?

Does it boot without the drives installed?
If so, install them each one-by-one until it fails again.

considering taking everything out, hard disk, if there are multiple memory, take out and test with one stick at a time

That Reddit video is accurate except my hand is much better looking. I'm practicing to be a hand model. Haha.
It doesn't boot and no beeps. It shuts down before it has a chance to boot up. The fan will spin at low speed for about 1 second. All the HHDs are removed and it has a good memory module. I've conducted about 5-6 sessions with tech support and they believe its a faulty circuit on the board. I'm hopeful that its a capacitor, resistor or other easily identified replaceable component. I need help with troubleshooting the board, if possible.

@scfirnatine suspect it could be mosfet shorted, but can try looking at there first.
