CPU is fried. Oh well, onto the next coffee damaged one that came in this morning. Go ahead and mark this closed please.

I was afraid you were going to tell me that LOL. Maybe I'll get lucky and hopefully find bad resistor in the SPI, if all that goes well, then I guess I will call the board dead =-/ I will let you know how it goes. let me get to probing the SPI.....

PLT_RESET_L shows 0v with Logic Board plugged in and turned off PLT_RESET_L shows 3.33v pulsing on and off with Logic Board on

I am talking about with the heat sink on. I learned my lesson 2 years ago on a Mac Logic Board especially these, not to run them with out the heatsink as it will damage (which happened in my case) the CPU. As for you saying "not recommend to force CPU", I am sorry I worded that wrong as I was...

vCore and coils steady 1.68v and forcing the board off CPU doesn't stay warm.

Hello all, This may seem to be very weird, but I repair daily liquid damaged MacBooks and never have an issue. Now after all this time, I get an A1466 with no liquid damage and all signs and rails show there shouldn't be a problem. Just not getting chimes and I plug in a mouse and it just...

Nevermind, BIOS was corrupted. Running like a champ

Hello, This is the weirdest thing I have come across. Brought it back to life after water damage repair as well as putting on 2 donor SMC and I get full bootup to the customers login screen then after 10 to 20 seconds it just shuts down. I am unable to PRAM reset for whatever reason. Any...

Q9706 Pin 1,2 - 12.5v Pin 3 - 4.3v Pin 4,5,6 - 12.5v BKL_EN - 3.1v BKL_PWM - 3.2v BKL Line LCD Pins 2,3,4 - 3.3v Pins 21,22 - 0.6v

Thank you for the suggestion, I didn't even notice the through the hole to other side was bad :-/ I have the 3v on pin 2 of R9731 still no backlight. I'm beginning to wonder if this board is just hopeless

pin 2 of R9789 - 12.03v then drops to 0.1 pin 1 of R9731 - 0v pin 2 of R9731 - 0v What resistance do you measure on R9731 - 301K

No beep at all on all the Pins you asked.... I should just go run this over with my SUV a few times, pick up the remains and burn them and then bury it..... Just for the heck of it I replaced C9782 as well... Pin 3 now shows 4v still no backlight....

THE ACTUAL PART Q9706 Pin 1,2 - 12.5v Pin 3 - 12.2v Pin 4 - 12.5v Pin 5 - 12.5v Pin 6 - 12.5v

Let me check because I just realized I am so fed up with this board I was measuring U3990 UGH... Why isn't there a head bashing wall emoji! Let me recheck....

Measured in diode mode

C9782 no short on either pin Q9706 Pin 1,2 - 3.17v Pin 3 - 3.3v Pin 4 - 3.3v Pin 5 - 0v Pin 6 - 0.6v

LCD_BKLT_EN is 3.2v F9700 is good with 12.5v on each side and PRAM was done three times in a row, no changes.

BKL_EN is 0.16v BKL_PWM is 3.3v Yes image is in background

Ok, this board is really upsetting me, remasked the area, put a new LP8550 and short to ground is gone from all BKL points, now Pin 21,22 on LCD connector is giving me 2.4v as well as Pin 1 on D9701

dukefawks, I greatly appreciate your time, I found out what is wrong, I need to re-do the solder mask for the LP8550, it didn't look to bad the first go around but I pulled it again and yeah, you can't make out where the pads go. So I have to make a blackout stencil and uv some solder masking so...
