No power on, No LED on logic board
Hey guys, Today I need your help!
I have an iMac late 2013 with 11.7 Volt of Logicboard (J600 plug) .
No diagnostic LEDs. System no Start
I still have to measure other small plugs.
does one have a tip? O_o.
iMac A1418 (21.5 Zoll) ME087D/A (late, 2013)
i5 4570 ,NVIDIA 750M , 8 GB Ram
u7600 does not give 3.3 and 5v.
pin 16 = 11,8v
pin 18 = 2.3V.
pin 12 and 24 = no voltage ..
should I just try to swap the ic or is it a broken elko?
There was a short to PP3v3 S5 line. because of defective C9480, C9615 and R9612. The distance is closed. I think the ISL62383C did not survive ed:(
u7600 is new :)
Unfortunately, U7900 does not output 3.3v. now he has to be swapped :/
Ist dies eine gute Frage?
