Well ordered a PSU 1921 it gives out 11.96 when plugged in. Still nada when hitting power on button. So total strip down. Power button board clean no signs of problems and multimeter gave ok reading. Then noticed that where the button plugs in on board had some discoloration. Looked up along the R15’s and the 2nd up V_CPUCORE had 2 shirted components. They are marked in red and smaller of the 2 has like ones end parenthesed in green. Says can use ones off a Xbox one s but can’t find the exact small on any help and ideas would be great.
