i'm searching the part marked in the picture.
is there any chance to find a new one ?
the old one is dead - it gets hot after the iMac is switched on - the iMac wont start, some times it shows the red led - sometimes it switches immediately off.
after that, i startet searching on the logic board and burned my finger tip on this part

Hi,
To get the part would be one problem, the bigger problem is that the solder points are under that IC. Without the proper tools there is no chance to solder the new part in place, or even desolder the old part. BTW, that an IC gets hot doesn't necessary means that the IC is damaged, maybe a different part is damaged and the IC gets hot as a result of that.
这个答案有帮助吗？
since i repaired cell phones for years (some time at a nokia shop and the rest self employed) - i know how to change bga's - even reballing would be not the big issue - surely there can be another problem, but since there are no real "service manuals", i can only use the "trial and error" method. surely - there are some apple service manuals on the intenet, but they are useless in those cases.
Ok, the first problem is out of the way. Could you make another photo of the IC so we can read whats written on top of it. Maybe we can find a data sheet of the IC and see why it gets hot.
I will open the 20" later - it's 3:33 in the morning ;-)

well i think it's time to close this one - didn't fix the imac, the only way to get the part is from another imac...
