Bought this IMAC broken and am trying to fix it. It looks like a couple of chips are cracked and or broken off on the logic board. If anyone could tell me what exactly these things are and possible where I could find some new ones to solder on. Thank you, David

@dclnine you are correct. One is T4000 and the other one is T4025. Both of those parts are LC607-AP-AFT453220M-171-T001 pulse transformers made by TDK. Sorry datasheets etc. no easily found.
