Yes i get voltages.

When everything is connected. the fan goes max instantly and then reboots after sometime. macbook detects on AC2 with a padlock sign. Tried DFU Revive. Stuck at Installing Software Midway with Fan spin at max. Then eventually it got cancelled automatically. Now it is stuck at 5V. No Fan...

Checked the resistors. the readings are okay with one leg removed - match with the schematics. RC712 is 126 kOhms. Removed CC719/20. Still the same readings

Still the same.

Resistance Across Pins RC709 is 15 Ohms RC710 is 0.8 Ohms RC711 is 2.2 kOhms RC712 is 35 kOhms RC713 is 27 kOhms. Traces look fine.

PPBUS at 8.6V. R2861 was busted. Replaced it. Device will not turn on. NO FAN SPIN. U1950 Pin 2 3.4V Pin 8 is 3.4V Rest all are 0V. L7430 is 0V. Diode reading is also 0.120.

PPBUS at 12V. Corossion near UC710 and UP7101. PP3v3_s2 is 0.4V - No shorts. PPBUS_AON_3VS2_VIN_ISNS is 12V P3V3S2EN is 1.8V i Replaced UC710. Now PP3v3S2 is 0V. Others remain the same.

Please reply

i have verifird that they are universal. Machine will not go in DFU. SOC_FORCE_DFU goes high to 1.8V but still nothing on AC2.

MFDF5804 and MFDF5808 are universal and interchangeable?

Injected 1V. nothing on the thermal camera. slight heat i think on the cpu. i assume CPU gone.

i removed both the caps and U7700. the short still remains. CPU gone ? i get 8V to 12.3V at PPBUS as well.

Machine came in for Display repair. Replaced LCD only and checked and it was fine. after a day it is not turning on. Drawing 5V with very low amps cycling between 0 amps to 0.45 amps. Thermal scanning shows on point on U7700 heating up. traced it to PP0V805_S1_VDD_FIXED. Diode mode to ground...

It wasnt burnt. A cap near it exploded. Ppbus_hs_cpu was shorted.

U7410 (MFDF5804) shorted. I didnt have the same ic so i replaced it with MFDF5808 which essentially does the same work. After replacing MacBook turned on with high fan speed and lagging as if the cpu throttle. As per my little knowledge this chip has something to do with CPU throttle. Need...

Replaced UF260. So now have to do thermal scanning on both USB ports in case of CD321xx failure from next time.

When plugged in to the port corresponding to UF400. UF260 is heating up a lot. although no shorts.

didn't work. After removing U8100. PP1v_s2 is still .110 at diode mode. Taking very little amps and nothing is heating up on the thermal cam.

U8100 heating up slightly at a single point along the left side. I think it's the PP1v8_s2 point. this line goes upto 1.8V and pulses. Can DFU solve the issue ?

The chip was bad. Replaced. Now again UF400 starts rebooting and UF500 is stable. I do no understand. Once is CD3217b12 and the other CD3217b13. Can that be the issue ? Replaced both with same CD3217b12. Still issue persists. Now removed the fuse. Getting 12.3V stable at Pin 1 on both ports...
