PPBUS_G3H seems a bit low, also PP3V42 should be stable, I guess this is liquid damage, could be corrosion under SMC....

widespread liquid damage, none in smc area

smc reset probably fucked, or jtag

I remove every jtag that comes in, will check smc_reset_L when I have another go at it, I've already marked it as not fixable, customer donated the whole laptop

PPBUS is too low so probably SMC not running. Dead SMC or crap under/near it.

thanks for the reply, I will try again when there isnt 10 jobs waiting
do you know any site that sells smc and iphone stencils (besides alishitexpress)

Ebay and Ali are the only ones I use.
