on 200 ohm scale, I get 3.5 ohms on 17/18 and around 20 ohm on 27/28

u7000 17/18 27/28 both 0 resistance

idk wth is going on but i checked too many bad looking components. this one going to junk pile.

hey all i got a machine it got green light no fan spin but the ppbus_g3h measuring low 4.10v? pp3v42_g3h is good 3.4v no sign of water damage what can cause this?

short to ground on pp3v42? how can it still power?

ok so no display. pin 2,3 no voltage but 4 is measuring 3.33v

its booting without it. I will connect to a good machine see if display working too.

ill try now john

Not sure what it was my workmate washed in ultrasonic and pram few times and sound came back. not sure what was causing the issue.

Hey all this one came water damage. lvds was bad and ppvout_sw_lcdbklt pins were gone. SO i ran jumpers and turned on the macbook and boom - instant smoke. So i go over thunderbolt and check all components around u9410 and make sure everything is good. Re done the u9410 now v2 with jumpers to...

Sound is back. Thanks please close

hey guys, This one had no power/no boot. Upon closer inspection i found some corrosion under the grey spongey type sticker next to battery connector. Once i peeled it away i noticed some corrosion and tested components to find short on one of the caps. it was corrosponding to pp_audio_ch and...

Yeah i already peeled sponge, this is 2nd wifi module i change also. It works sometimes and then other times just disappers. I have inspected connector and pins everything looks good.

connector looks good. ALS?

Hey guys. Everything works well except the issues mentioned in the title. I have tested the resistors around fan connector. all seem well. also changed q5660. fan still 100% where to hunt? is this common problem?

same issue here. i was just looking at one. hate to change keyboard only to find out its not the issue :eek:

No sign of water damage ASD fails on: Fan motor exhaust test #4 - ERROR -- 9 Quick fan motor test #5 - ERROR -- 7 Fan motor: exhaust test #21 - ERROR --9 im getting 5v and 3.3v @ u6010 pp3v3_s0_fan is .5v? <--- shouldnt this be 3.3v? Thanks guys

n00b question,... can smc be replaced?

ah wow. :( RIP mbp.
