iPhone 12 Pro SHORT on No BOOT
I have an iPhone 12 Pro which does not boot up. I have checked VDD_MAIN I had short which I have cleared.
Connected to DC Power and started boot. On the DC Power I can see 31Amp then straight jumps back to 0 than 51Amp than jump back straight to 0 than 165Amp then straight jumps back to 0.
I have put it under Thermal cam And I can see that part of the PMU flashing indicate heat.
I have checked the PMU power lines and found out that PP0V6_VDDQ6L_S1 is SHORTED (Diod Mode 0.000)
After this I have removed all caps on that line but all where fine no broken caps and without them short still there.
After that I removed PMU to check if its bad or not. Short on that line is till present.
Could be the CPU??
Ist dies eine gute Frage?
