R1210/2 = 3.3V R1210/1 = 0.36V It got correct resistance 1K Ohms. Removed shield from J9600 and there was liquid as well and pins 44, 4, 6 looks affected.

No pulse at PM_PWRBTN_L. It stays at stable 0.367V.

Small liquid on C6553 When all connected go 19.5V and 2.5A on charger. No fan spin, no chime, trackpad no clicks. PPBUS_G3H = 12.56V PPBUS_HS_CPU = 12.56V PP3V3_G3H = 3.41V PPBUS_HS_OTH5V = 12.56V PPBUS_HS_OTH3V3 = 12.60V PPBUS_S4_HS_TPAD = 12.60V PP5V_S5 = 5V PP5V_S4 = 0V PP3V3_S5 = 3.32V...

Board got liquid damage on U7210 area, C3724, U3701. 5V and 0A from charger. PP3V3_G3H 0V and 0.380V in diode mode. Any idea?

Board got liquid damage around U7410/20/30 and J8500. Is there anyway to check if CPU is still fine? Other damaged area is J5100, U3200, UB300. 5V 0A on charger. Found short (0.003V in diode mode) on PPBUS_HS_CPU. Started to remove U7410.. etc one by one and when U7430 was removed short gone...

R6131 on SPI line was bad - replaced and all works fine now. Many thanks and have a great weekend :)

Liquid damage on J6100 area. Light on charger, no fan spin. J6100 removed. 5V S5 was pulsing from 0V up to 5V every second. There was short on PP5V_S4RS3 - C7550 was bad. After that got fan spin, no chime, no image/bkl, USB activity works, caps lock LED off, CPU warm. There was no corrosion...

CD3215 batch was faulty :/ Used another CD3215 all works fine now on both sides :) Thank you very much :)

PP1V1_UPC_XA_LDO_BMC got 0.15V (0.460V in diode mode). Rest LDOs got correct voltages. Changed CD3215 and still the same issue - tested with board only (no battery).

Charger (genuine 87W) was working only on one side of USB C port and there was 5V and sometimes 20V (was charging fine but when connected any USB device was not visible in macOS) but when use other side of charging cable there was nothing on ampmeter. Replaced CD3215 and both side are working...

Board had small liquid damaged repair long time ago on backlight circuit (fuse and LED driver has been replaced). No new liquid damage/corrosion visible. Magsafe LED - on Fan spin = yes Chime = no Image = no Backlight = no USB LED = yes Caps Lock LED = no PPBUS_G3H - 8.60V...

After contact with liquid LCD connector on display is melted. LCD connector on logic board in perfect condition. Logic board looks clean. At first stage I disconnected LCD cable and connected external display via USC C and there was Apple logo, progress bar but after w few minutes restarts. Went...

Speaker amps replaced, palmrest replaced and all working fine. Many thank for help :)

When located PM_PWRBTN_L on the board then I saw Q2120 looks not too good. Replaced Q2120 and got fan spin, no chime, nothing on display, caps lock LED off and after a few seconds single sound BEEP.

PM_BATLOW_L - 3.31V Got genuine 85W Magsafe 2 charger. tried with two kwon good batteries and same issue.

Liquid damaged battery PCB and liquid damage around U7100. There was no light at all, replaced U7100 and got light on charger. U7100 resistance: 17/18 - 3.6 Ohm 27/28 - 38.4 Ohm (is too high) PPBUS_G3H was at 4V R7122 had 40 Ohm - replaced and U7100 between 27 and 28 is correct at 20 Ohms buts...

Yes, same issue

With disconnected camera the same issue (instant fan on max rpms) Diagnostics with the same error codes.

PPBUS_G3H no battery 8.58V PPBUS_G3Hbattery only 7.41V Diagnostics: There may be an issue with the fan: PPF003 There may be an issue with the camera NDC001 (camera works, but ASL is not working - can change keyboard backlight even in very bright room or torch - checked with another lid and...

Cant find any liquid. There was some repair done around R6061 so there was some issue with SSD - tested another SSD and SSD is visible. Fan runs at max RPM immediately after power on. Board + DC board only still same issue so dont think it is linked with trackpad and ASL. Mac is not laggy. In...
