2 Asus PG27UQ Monitor doesn't turn on at all
Issues: Wouldn't turn on so I unplugged everything other than then power supply.
Troubleshooting: I unplugged the power supply from the monitor and plugged it back in, the white light on the bottom (that signifies that the monitor has power) would do a little sparkle every time, but wouldn't stay on. The monitor wouldn't turn on either. Power button did nothing.
I tried this with 2 power supplies.
I took it apart to check if any of the capacitors or chips were obviously (visually) at fault, but I see nothing wrong.
Diagnosis? What would be the next trouble shooting steps?

@opewoewo add some pictures of your boards with your Question. This "the white light on the bottom ...would do a little sparkle every time" sounds like a bad component (Mosfet). Please ensure that the images are well focused and large enough to zoom into. 在已经存在的问题里加入图片

@opewoewo image 5 lower Left hand corner has what looks like 4 fuses. Check those for continuity and power when you connect the power supply.

@oldturkey03 I need to grab a voltmeter from the lab for this so I will update you tomorrow. I assume you mean to just connect the motherboard to power (through the PSU) on its own and then check all fuses are all continuous with each other and also that they exhibit a voltage right (otherwise how do i check for power)?
