I have 820-2936-b fan spins for 30 seconds and shuts of and starts again there is no water damage. No idea where to start.

I have green light so i have PPBUS_g3_hot and o have PP3V3_S5 also i have 3.3v for PM_PWRBTN_L and SMC_LID IS 3.3v and PP1v05_S5 i have but i don have so state on PP1V05

820-2530-a no PM_SLP_S4_L comes from MCP but what's powering the MCP?

I have 820-00138 and it doesn't give me an image but works perfect on external monitor so i checked the connector pins on the schematics and looks so confusing compared withe the other boards and also i have to use board view file similar to that board because is not available yet. Anyway i have...

SSD is working 100%

I have 820-00138-a board that someone else worked on it doesn't see the ssd on the schematics i was seeing the signals and i have 3.3v on pins 1 to 5 and 25 to 28, also i have SMC_OOB1_R2D_CONN_L but i dont have SMC_OOB1_D2R_CONN_L and SSD_PWR_FET_EN thosse 2 signals come from u3711 i believe...

I've lost power also for some reason green light stays for 50 seconds and after goes away

I've checked the J9500 is fine only thing i haven't try is different cable 821-1722_a

I've noticed that after i put the second good IO board i got chime when it was turning on but after there wasn't sound. Also after replacing the io board my fan run on highest RPM I've replaced Q6060 and i checked R6061

I have 3 good IO boards. I can't figure it out what i'm missing

who's this?

im kinda confused on this issue. Is the audio chip located on the small board together with the mag safe? I've checked U8040 has enable signal on out i also have PP1V5_S0SW_AUDIO also U6410 gets 5v but nothing on output also MAX98300_R_P and MAX98300_R_N are missing or they suppose to miss not...

I want to buy good Bench Power Supply Any suggestions. I'm looking at BK Precision 1687B not sure if its good ???

Thank you. Do you know what is the reballing station that goes with those stencils ???

What's the proper SMC reball stencil ? 0.25 or 0.3 i found one on ebay http://www.ebay.com/itm/400644809049 and it say has pitch 0.5mm is that good for smc???

0.001V on all of them

I have 820-3332-a water damaged board has orange light but doesn't turn on. After measuring the power rails I've find out that i have few power rails missing P3V3GPU_EN, P1V8GPU_EN, GPUVCORE_EN and i think they all coming from the SMC if im right ????

I have orange light but doesn't turn on i've started measuring all power rails and PP1V5_S3RS0_FET_ISNS was missing so on XW7805 in pin one i measured 1.5 v on the other side was 0.001 so i think that's my problem. What's your opinion ?

I have water damage 820-3332 i found out that XW7805 but i can't find what exactly is that component on schematics usually have part number but not on this on im assuming is diode?

I don't know because that board was in another shop before i got it, and the costumer took it back and send it to me. You think is the BIOS???
