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 !

My first guess would be a smd version of a tl341 reference ic

Re: Help identifying PS4 power supply component burnt

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

Re: Help identifying PS4 power supply component burnt

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.

Hehe sorry I'm a bit dumb , just trying to learn . Tested dnp012a and seems broken , some legs shows continuity with ground, removed and there is just one leg to ground left . Going to purchase required parts to see if power supply comes to life, will post results soon
