Always 0V PPVCORE_s0_cpu, U7400 fine i've probably fried CPU because GPU is proximity (overheat)

Solved dead battery

I will try another battery no short on PPVBAT

Another board with liquide damage, work with charger only (tried another charge of course) PPBUS_G3H 8.5V only with charger present with battery or not diode mode pins 4 5 of J6950 without battery 0.469V pins 1235 no voltage present R5380 and R5381 2K voltage with battery pin 6 0.6V...

tried without vram same problem cpu dead for you ? what check

cpu not too heated because for test i've reflow gpu first same temperature before replace, and cover CPU with adhesive high temp, Balls touch under vram can cause this ?

find cracked ball under vram reflowed and Without GPU same problem,

date code 1532 garbage ^^ ? What are the good date code for you ? I will try without gpu if board start

Ppvcore_s0_cpu 0v (short to gnd) :/ gpu vcore up to 1v about and 0 when fan stop SMC_CPU_HI_ISENSE 0.8V ALL_SYS_PWRGD up to 3v about (too fast for read next)

Before replacing gpu i've heated gpu and board starts ok After replacing gpu twice, same probem, fan spin 3second and stop loop Good light, orange light ok Glue under vram removed before and checked balls after Garbage gpu? No composant missing or burned PPVIN_S5_HS_GPU_ISNS 12.56V...

replace again U7000 same problem, replace again new smc again it work thanks solved

smc replace exactly same problem try again replace U7000 ?

In diode mode pin 2 of R5280 0,551V and for pin 2 of R5281 0,537V battery indicator not work when pressed, work from another good board know

now replaced U7000 board startup without battery with ppbus 12,25V but battery no charging and no orange light, no power from battery PPBUS_G3H line battery only 10,80V

resistance to GND on PPBUS line 1,06M and decrease, resistance around U7200 area fine board startup only if battery plugged with charger, ppbus at 10,95 with battery plugged

PP3V42_G3H 3,405V PPBUS_G3H 0,478V R7021/22 9,8 ohm R7005 20,3 ohm R7010 9,32K R7011 30,15K R7052 0,1 ohm R7051 2,4 ohm 17/18 of U7000 3 ohm 27/28 of U7000 20 ohm R5087 297K (need 470K replaced same value 297K) SMC_BC_ACOK line 294K CHGR_ACIN 3,98/4,01V light fluctuation slow CHGR_DCIN 16,75V...

ALL_SYS_PWRGD resistance to GND 21.23K and voltage increase and decrease 0V and 3V loop ALL_SYS_PWRGD_R 0V and resistance to ground OL

no PPVCORE_S0_CPU 0V Light fluctuation with multimeter but too fast to read values and no power from battery, it's possible problem with bad smc again ? what does it mean CPUIMVP_VR_ON ? because he goes at smc

R7402 182kohm R7403 150Kohm 12.4V at pin 1 of R7402 and R7403 and 0v when board stop

U2600 replace same problem
