Hi, I have one here that would kernel panic when running ASD OS but not every time. ASD EFI passes with no errors. I removed the logic board and the only evidence of liquid I could find was a tiny spot of corrosion near the LCD backlight connector on a test point that was just surface corrosion...

The macbook boots up and runs. ASD EFI passes but ASD OS has 2 thermal errors "unknown result code -- test failed" and the fans are constantly running full speed. This macbook had liquid damage, I replaced a couple of resistors near the SMC R5092 and R2502 and ran a jumper from pin2 of R5092 to...

Hi, I have dead 820-00840. It had liquid damage around U2890 which I cleaned up and ran jumper wires etc. 5V on the USB C power meter. I have: PP3V3_G3H = 0.17V PM_EN_P3V3_G3H_R = 0V Neither are short to gnd. Any help from here would be appreciated.

Hi, This is a liquid damage board. The board turns on but does not POST. I have all the S0 rails except PPVCCGT_S0_CPU AND PPVCCEDRAM_S0_CPU. I'm struggling a bit to figure out how the voltage regulator circuits on these newer boards are supposed to work. Any help would be appreciated.

Hi, I have a liquid damage logic board. One of the RAM chips was badly corroded so I reballed it. The macbook will boot and pass ASD EFI but if I try to boot any OS, either ASD or a USB test drive it just cuts out. Any ideas where to start? Cheers, Alex

Hi, I have a board that will boot from ASD flash drives but it won't boot from my USB 2.5" SSD macOS test drive. The other problem is that when the wifi card is connected, it won't boot. I'm guessing it's to do with the BT side. Tried with a known good card. I also noticed that the USB...

Hi, I have an 820-00840-A that had a liquid spill. Q7900 is blown, it is a TI CSD58889Q3D according to the schematic. I can't even find a datasheet for that part#, does anyone know where I can source some of these or something equivalent. A datasheet would be nice. Pins 1 and 2 are shorted to...

Hi, I have a board here that won't power on after a liquid spill. U7650 and Q7660 were badly corroded so I have replaced them. After cleaning the board in the ultrasonic cleaner, the rest of the board looks OK. It's missing PP5V_S4. I'm testing using an original Apple 87W USB type C charger and...

Hi guys, I have an 820-00928-A with a 0.5R short to ground on PPBUS_G3H.I removed F7000 and F7001, the short is on the pin2 side. I injected voltage into the pad of where pin2 of F7000 goes and wound up the voltage. It was drawing ~4A at 1.8V and the only thing warming up is the CPU. I'm...

Hi Guys, I just got a mid-2017 15" Retina MacBook Pro in for repair. The logic board has some liquid damage. I'm not having any luck at all finding schematics and board view for this 820-00928-A so I wanted to ask if anyone knows if this is available anywhere or if it's just not out in the wild...

Hi, I have an A1278 that came in with no power (liquid damage). I noticed while I was inspecting the board that there were signs of rework there already and I really don't think this is a customer diy type of thing but the reason I am posting here is that the SMC is completely flat against the...
