My Apple Cinema Display PSU has been fried somehow, and now I need to replace the ICs which look short. I cant identify them for a replacement. Hence Please share High res Images of the PSU board from behind (front is where the Power Electronics are). Thank You
Ist dies eine gute Frage?

It looks like one of the IC’s blew up on you on the main logic board (Apple P/N 661-4823) I don’t have the schematics or board view drawings to aim you to the discrete part. Maybe someone else can help you on that. It might be hard to find these older chips but I’m sure you can locate a logic board working or even a dead one to get the part from.
Hint, look under details for the service guide.

Thank you sir. Also its not the logic board its the PSU.
"Hint, look under details for the service guide." checked but nothing related to the PSU
@oldturkey03 & @aaryansarwankar -The PSU is likely fried from a power spike the second image looked like the main logic board which is a different chip failure. The first and third images are the PSU.
Clearly I was mistaken. While it might be possible to find the chips it’s likely safer to just replace the PSU
@danj yeah you are right, as i live in India sourcing the chips might cost me less tho.
all pictures are of the PSU,2 different ICs have been shorted out.

@aaryansarwankar that is either a AS324M-G1 or a TSM104W quad operational amplifier and an adjustable voltage reference used by LiteOn on their power supplies. You are right, it is definitely not on the logic board :-)
Let's see if we can find the proper board.
