Oh wow. I need to read up and study more on voltage. Thank you so much again for your experience and expertise. Looks like NAND is shorted. BUmmer :(

I used 6A and 1v and the only thing that heats up is U8700 (NAND) Am I screwed?

ohm value 0.9 I looked with infra red camera but only saw U9000 heating up so thats why I took it off but there is still a short. 2.8v and how many amps should I use? Thank you for the help!

I have a short on PP2V5_NAND_SSD0 History: Saw only tiniest bit of liquid on U9080 which caused a short on PPBUS_G3H_SSD0_SNS Replaced U9080 Short gone Still short on PP2V5_NAND_SSD0 Removed U9000 and still have a short on PP2V5_NAND_SSD0 I see plenty of caps to look at and of course the...

aHHH. OK. I don't like luck. Where would be a proper place to inject power? I see Louis trying to find shorts that way but he usually takes off a component to figure out which side of the line from that component is short. It was an older video though maybe there is a better way. What would...

L6900 PIN 1 = 3.36V. yAY! Anything else I should check before putting the board back into test?

PP5V_G3S = 5.12V

WOW. I GET 20V NOW AT USBC!!!! PPBUS_G3H = 12.3

Well I did inject the voltage and found C6455 - PPBUS_g3H_SPKRAMP_LEFT was shorted. I'll test power rails now.

Would F7000 be a good place to inject 13.1v on PIN 1? If so how much amps should I set it too, same as charger 4.2amps?

Or if I find components that are closer to 0.00 in diode on the shorted rail should I inject voltage on those components and see what heats up?

What is the best way to find that short given that all of the line is shorted? I'm still having trouble with that. I know I could start pulling components off but that would be a lot of work. Is it by voltage drop at different points or...Diode mode? This is something I need to brush up on and...

Yep. Confirmed. F7000 = 0.00 both PIN 1/2

Crystal. Thank you and I will get better at understanding the instructions. You are the Man! The USB-C Macs are new for me. 3V3_G3H = 0.383 (DIODE MODE)

I did read the post. I misunderstood what you meant and forgot to put AUX_DET. YOU"RE are a machine!! and I know you have this whole forum to help out but can you elaborate on what you meant by "cannot get 20V on USB-C power port. Post first diode mode there" That will help me better...
