Hi there, I got a 820-00165 with a liquid damage around U7600. I'm in S0 State but ALL_SYS_PWGD is missing because of low PP1V05_S0. Already replaced U7600 and C/R/Q7630. Resistance to ground on PP1V05_S0 seems good (320 Omh). Here are the voltages of U7600: Pin 06 :1.8V Pin 12: 5.1V Pin 16...

Yes I did. With another 2015 Board. Works fine...

I will replace and check J8300 again. The screen should be fine - it's the original one since I'm pretty sure the MBP was never opened before

R8300 is good, checked the traces - they seem to be fine too. Just tied a Screen for a late 2013 MBP - I know that it is not compatible but here I get an Image (without backlight) and stable 2.8V on LCD_HPD. Tried another Known working screen for 2015 MBP but same issue here with missing LCD_HPD.

Hi there, currently I'm struggeling with a MBP 2015 15" (820-00138). It had some corrosion in the are arround the LVDS connector (on both sides of the MLB). Now the USB port is not working and there is no internal display. Works fine with external display so far. PP5VR3V3_SW_LCD goes high for...

The Board is taking 290mA

Just received the UV Cure paint today. Isolated the short to ground but still got problems with the U7100 I think. I don't exactly know where to Start to Look for the issue. Would aperciate some help what voltages should be present here. I'm in S0 state but no usb activity or display.

So it was just the connector... everything Works fine after replacing it ?

I think it might be the battery flex connector on the Logicboard... I did some continuity measurements and recognised most of the pads arent connected to the battery board. I will try to replace the connector tomorrow... This will be fun :-D I hate soldering those connectors...

When trying to connect to a WIFI nerwork it stucks connection to it. If I use my Wifi Hotspot without WPS key it connects but breaks with an error while loading (displaying 1h 40 min as remaining time) The MacBook seemed to work when I bought it (very slow but macOs was installed on the pictures...

Ah okay, thank you - didn't know that :-) I just did the DFU restore but the problem persists :-/

Fans are even turning apinning Max if keboard/Fans connected only and nothing else.

I just replaced the coil but same Problem. Tried also with disconnected Webcam... also without success. Currently I don't have a second woking T2 macbook for DFU restore ??

I just sah that i was not the first one working on this Board. Looks like a water damage on the lvds connector. There is a coil missing (L8504) für PP5V_G3S_ALSCAM. Could this be the reason? Missing connection to the cam sensor?

And the Macbook doesn't Start from Known good battery. But stays on if I Start it with charger and unplugged the charger afterwards

Hey, Im struggling with another 820-00850 Board. The MBP ia very slow. I received it with formatted SSD and I can't even install MacOS. It stucks on status "Less than one minute..." with progress Bar at ~25% I already tested the Board in a Known working case - without luck. I recognized that...

Hello, currently I'm working on a water damaged 820-00850. There was corrosion on and around U7100 with a broken pad No 25. After trying to restore the pad i scratched too much and opened the underlying layer (GND). PP7103 is not shorted to ground but pin 25 of U7100 is now... Any ideas how the...

Hey :-) I got a 820-4924 turning on, CPU_VCORE is present but I don't get any USB activity or POST. PPBUS_G3H: 12.6V SYS_PWROK_R: present CPU_VR_READY: present PLT_RESET_L: present CPU_VCCST_PWRGD: present PM_PCH_PWROK: present PM_PCH_SYS_PWROK: present already tried reflashing SPI-Chip with...

It's working fine now with new trackpad flex :-)

I think it's the trackpad flex... i can reproduce the wrong temparature sensor value by pressing on the flex at the side of the trackpad (with the old and a known good one). So I will wait for the new flex cable and report her if this solved the problem :-) Thank you!
