Before removing SMC I took a look at the power dc and noticed this, I don't own another can I fix it? What is it?

Can I use 00163 SMC looks the same

PP3V42_BUS_G3 = 3.30v PP_BUS_G3= 12.23 SMC_RESET_L= 0,831v SMC_BC_ACOK= 3,00v Post diode mode 3V42_G3H= 0,025

I downloaded 00163 and realized that there was no capacitor near SMC or C3550 (on 00163 boardview that corresponds to reality) and it was short-circuited. Then while I was checking U7100 I touched C7102 with C7116 and I had to replace U7100, all as before but I have low insulation on PP3V42_BUS...

But is there more than one version of this logic board? Because the scheme is slightly different

I fixed a connector to power everything, I checked SMC and it seems to work I switched to u7100 and on ACIN I have 4.69v and on SMC_BC_ACOK I have 3v the ACIN value seems high to me, shouldn't it be 3.2V?

nothing, however, I begin to suspect that it is the adapter unfortunately I do not have the same head for the counter one

3V3_S5/SUS= 0V Y5110 DC voltage ON PIN 1 IS 1.40V PIN 3 1,22 V

SMC_RESET_L= 3.38v

Hi, i don't get the precise green light that the Magsafe is not original this is what i have: L7095 3.43V L7130 12.25V L7195 5.50V L3095 0V L7720 0V L7710 0V L7520 0V L7630 0V L7430 0V L7310 0V L7320 0V L7330 0V

I reballed all the rams, now it works perfectly

I suspected that he had been reflowed at the ram because some capacitors were missing, I began to detach on one side and I was lucky that after 3 modules the short was gone

I removed 3 ram modules disappeared the short and the card started I suppose a reflow was done and they shorted pp1v05_S3

To confirm that it is the CPU, what should I measure?

How do I see the ram that is short? In fact, I found a missing capacitor near a ram

So a short on the CPU? Either first I have to check U7801 or remove R1120 and see if the short is interrupted

I lifted L7330 the short remains on the 2nd I checked all the leveling capacitors and don't pull down PPDDR_S3_REG at this point is something after the boardview would look like a rhophore under a ram, lifted the ram?

0.001.0 Ω

Then update I found a fault on U7940 now I have PP3V3_S3 and the 5v_S5 I have the 3v3_SUS but the short on L7330 remains I also get 1V05_S0

PP3V42_G3H 3.38v PPBUS_G3H 8.38 SMC_RESET_L 3.32V PP3V3_S5 3.3v PP5V_S5 5.0 V I don't have S3
