First check the power supply or swap another.
Clear CMOS jumper or remove the battey
connect only power 20 or 24 connect and test power on. no off? (no video because no power to cpu by 4 pin or 6 pin connector)
plug 4 pin connector and test power on. if on and off check cpu power section (mosfets) if burned one pls remove ... you can test short by touch the mosfet by finger (burning heat)
