yup i thought as much. crap board.

Odd that the board powers on and still no green light. Seeing how you have bcacok... i would suspect smc being bad seeing how it wont charge battery reflow it or replace.

My bad 18 reads 0.010

On j9000 Pin 17 = 242 pin 16 = 0 not sure what you mean before it but if you mean before it reaches l9080 then its the same results. Without l9080 its 0 on both pins

Reprogrammed the bios with a clean me and still nothing.

to this day people will buy and use 2010 hell even 2009 machines thats close to 10 years now. people can probably still get away with servicing and selling 2012- 2015 machines for another 10 years. plus you never know what can happen if right to repair passes. either way i can still see people...

All resistors and traces on spi termination to pch and u6100 are fine.

pin 8 = 526 pin 9 = 526 pin 11 = 530 pin 12 = 530 pin 14 = 532 pin 15 = 532 so i think i found the issue. theres a short on pad 1 of L9080. even after removing it the short is still there. by the looks of it i can see the only route that pad takes is to the gpu is this board fucked?

i do get a pulse on vcore also pulse on 7 and 3 of u1950 3.3v pulse new bios did nothing

l9080 is ok i do get usb activity it works with external monitor and im testing with a known good lcd pin 8 = 3.86 mohm pin 9 = 3.64 mohm pin 11 = 3.83 mohm pin 12 = 3.79 mohm pin 14 = 3.85 mohm pin 15 = 3.86 mohm

I get a chime and a backlight but no image tested with a known good screen and no luck i just get a black screen. voltages on pins 2,3,4 of j9000 are 3.2v

ALL_SYS_PWRGD Pulses PM_SLP_S4_L Pulses checked all the coils only ones that didnt pulse were L3095 and l7701.

i do get a reaction PM_SLP_S5_L spikes up t 3.3v when i short r5115 PM_SLP_S4_L spikes up to 0.72v

RTC_RESET_L = 3.3v PCH_SRTCRST_L = 3.3v PCH_CLK32K_RTCX1 = .41v PCH_INTRUDER_L = 3.053v PCH_INTVRMEN = 3.2v I do not own an o-scope any other way to check? i suppose if thats the only way to get this working ill have to get one. what do u suggest?

We still got at least 10 more years before we all go homeless or endup working a full time day job not too bad if u ask me. Gives us time to keep building clientel too bad i started late but its pretty cool working on my own terms and working my brain every day. Who knows maybe u all can become...

Using Original Apple 85W Charger PPBUS_G3H = 8.56V PPBUS S5 HS COMPUTING ISNS = 8.57V PPBUS S5 HS OTHER ISNS = 8.57V PPDCIN G3H ISOL = 16.83 (FLUCTUATES BETWEEN 16.39V - 16.83V) PPDCIN G3H = 16.27V PP3V42 G3H = 3.417V PPVRTC G3H = 3.325V PP5V_S5 = 5.02V PP5V S4RS3 = 0V PP3V3_SUS =...

SMC_ADAPTER_EN = 3.4v yes using a 85W original.

ok so i simulated a power on and pm_pwrbtn_l drops to 0V i did solder a wire between pins of r5115 to test.

it does change to orange pm_pwrbtn_l = 3.4v r1405 looks fine and has proper resistance

pp3v3_sus = 3.3v Pm_rsmrst_l = 3.295v Pp3v3_s5 = 3.3v S5_pwrgd = 3.388v
