[SOLVED]mac mini 1347 late 2014 wont power on

[ielectron]

the psu is 614-0515, i never diagnosed a mac mini before, took it apart, i measured the psu connectors on the board (compared to the GND, like on the heatsink) and i get no voltages on any pin, i guess that is a dead psu? or is there any trick wit the mac mini? i guess at least some 3.3 or 5V standby should be present.

Also i dont see the motherboard number, i was looking on ebay for the same pictures, supposedly its a 661-01020 | 639-00142?

ok, maybe not the psu, measured the psu connector on the board, all the legs are shorted to GND except the middle one with the via point

sorted, with the lab psu i sent 3V 5A, found a shorted large cap, removed, now works fine
