just the screen and the magsafe plugged in I get 0V on both pin 2 and 5 of Q9807
I am using a schematic that says 850-2523 not 850-2523b if this is my issue
I am not sure what you mean when you say "random measurements"
It does chime
No fan spin when board is out of casing, unsure if it spins when in case
No liquid damage
Yes good screen and cable
Yes I see apple logo
I use the tesfa red tape myself in combination with the stock, it doesn't seem too thick on air or mini or 1,2,3,4th gen full size.
For me no matter how clean the ipad is the stock just doesn't stick even just sitting on the shelf waiting for pickup. Too many pop ups with the stock stuff.
if shorting power pads = pin 5 of J5713 to GND then the fan spins for a short time. I am not holding wire for more than a few seconds.
Holding it for longer seems to kick the fan into high. I also do not have the board in the body at this time. I am unsure if this makes any difference.
Got myself a water damaged 820 2879
green light and no fan spin.
ppbus_g3h =12.59
pp3v42=present
pin 14 u7000 3.24 smc_bc_acok
3.34v pp3v3_s5
not sure if any of those measurements help.
kind regards
.5477 pin 5 q9707 diode mode
resistance to gnd pin 5 9707 99.3kohm
pin 5 9707 3.34
c9020 12.18
I also made sure that everywhere I could find PPBUS_G3H is 12.24. I had to run a jumper from backlight fuse f9700 to pin 4 on q4262 to get that up
changed a bunch of stuff I saw that was corroded...
Now, this might come off as narcissistic, which is the exact opposite of what I am trying to get across here but I am gonna give 'er a go anyhow.
I didn't graduate high school.
I had an 8088 way back when I was 12, I am 40 in April. I had no computer until I started modding original xbox a year...
even with different probes after measuring AAA battery properly it starts around 40 and just keeps climbing I'm sorry man I know you wanna strangle me and I would to if I were you.
I am getting this with everything except battery indicator plugged in if that helps at all
fuck, i was not measuring with lcd plugged in-had no idea there would be no voltage.-will now measure with lcd plugged in and report back
yes there is still image present after pram
tried pram reset now without battery indicator connected, no backlight
lcd connector area was also heavily corroded earlier. I have not tried a known working lcd
SMC_LID=3.442
