Been trouble shooting one wire... u6901 pin 5 no voltage and c6908 no voltage tested for short and says OL. Maybe this was dumb i tryed jumping from c6999 str8 to pin 5 on u6901 still no green light. but should i have jumped this ?
Ok so i plugged in the board into the chassis.... and it started smoking..... no apple logo no chime just white screen. i dont think i was supposed to jump this """"7085 has traca dmg coming from 16v pin ran jumper from q7085 pin 5 to r7020 f7040 now gets 12vs""""
I checked PP3V3_S5_REG i get .900volts so i think its time to troubleshoot that circuit
ok q7085 pin 4 gives me ol.. measured on both sides of r7086 get 6v on pin 1 0v on pin 2. R7086 gives me OL on pin 1 .500 on pin 2 diode mode... i replaced r7086same result
Ran 2 36 Awg wires from Q7085 to R7020. and its working fine now... What is the amerage between these 2 points ? Are these 2 wires safe or should i add more i dont have a thicker variation. Anyways mark as solved for now thanks aprendiz for the pads tip didnt know.
