[QUOTE="SweetDoug, post: 1783867, member: 397872"] ' ' ' Came across a 27" 2011 a1312 iMac, that won't start. Opened it up and poked around, and it appears it needs a PS at first blush. Does anyone have, or can point me to the Tech Manuals, service manuals on how to test the PS, or any tips. I don't even know where the LEDs are! I get power into the PS but only 25.8 volts on the 4th pin on the output, if that helps. Anyway, any suggestions would be great. Thanks, SweetDoug [/QUOTE]
