820-00165 has no liquid no signs of damage. ppbus - 8.6v pp3v42 - 3.42v SMC_RESET_L - 3.4v pp3v3_sus - 3.3v

C3530 was bad

no bluetooth i don't have oscilloscope

u3540: 1- 3.3v 2-.9 3-3.3 4-3.3 5-0 6-3.4 7-0 8-0 all traces good for j3501. customer said yesterday wifi stopped working

i've watched paul daniels video about 3 times and i guess i really don't have the pacience for reballing. is there anyone in us that would be willing to reball about 10 smcs for me? of course i'd be willing to pay.

PLT_RESET_L pulsing? - 0v not pulsing Did you try to start in SMC bypass mode? - yes no difference j6100 - is very clean Check all SPI Bus Series Termination resistors and their traces. - checked all traces and everything looks good. only trace i found was broken was to r5177, repaired that...

got a water damaged 00165 that has fanspin but does not boot. cpu vcore - 1.7v ppbus - 8.6 what other lines do you need? I'm completely lost with this one. is this damaged cpu?

aliexpress ad is saying smc is the same for 00165 and 00164 (11 and 13 inch). is this true? i thought each board has its own smc.

removed d6950 and completely lost connection to pin 3 on the port. ran a trace to j6951, replaced d6950 and now all is working. looks like a loose connection. thanks for the help :)

i did diode mode 2- .437 3-1.3

I don't have an oscilloscope but it looks like its pulsing at 3.4v diode mode is 2-.437 3- 1.3

820-00923 was liquid damaged and had a shorted cap on ppbus that i replaced. laptop turns on but does not recognize the battery. have tried new battery still same issue.

pp3v42 went short to ground for some reason. let me find out what went wrong

tried with new flex and board, no corrosion on j9500 pins pp3v42 - i have 3.417v i tested continuity from j9500 to smc testpoint for sysonewire smcbc acok -

820-3437 came in with liquid damage. pp3v42 was short and u7090 was corded. swapped it out and got orange light along with fan spin. thew it in the ultrasonic and now don't have orange light again. i tried changing u7100 but still no orange light. i checked diode mode on u7100 and no beeps...
