① Check soldering status on each major component.

② Check there is problem on major component  or not by eye.

(CONDENSER, FET, IC, Resistor) 

③ Check FUSE.

④ Check 5V,Va,Vs voltage

※ PSU Maker: 1) LGIT   2) LITEON   3) YUYANG   

※ If  happen Power board Protection,

check whether there is Short or Open on Y-SUS, Z-SUS B/D or not.
