    Help identifying PS4 power supply component burnt

    Hi guys!
    I'm in needing to identify a burnt component on a power supply model ADP- 240AR AA . Photo attached and marked . Any advice on replacing ? Maybe testing something before turning it on ? . Thanks !

      just a guess - given how close it is to the opto isolators - maybe a TL431 reference.
      but i never saw one explode - so check for other bad parts

              well there you have it, if 3 people say 431 then it probably is

              but i'll say it again - they shouldnt explode.
              so check for other shorted parts - specially the optocouplers

              btw, the letters TL, LM etc change depending on the make, but all 431's are interchangeable

                They are interchangeable, but may have different pinouts.
