Hi. Your quota for the PM has been exceeded :) I can see why :) Could you send us an email and we can reply with more details? support softio com

Hi. Removed fuse F7000 and appear to have the 5v0 to be stable (no more power cycling); PP3V3_G3H @ 2.94 volts and is steady (no power cycling). PPDCIN_G3H_CHGR @ 5.2 volts However, concerned about the following 2 voltages: TBA_CSI_P @ 2.8 volts TBA_CSI_N @ 2.4 volts Given that...

Thanks. Removed the current sense resistor R7020 (0.01 ohms) and the main 5v0 rail from the external adapter holds without shutting down. Also, the current draw is no longer zero but around 11 mA. In checking the diode mode method (first time testing this way) - found that C10G1 is being...

Hi. 1) after more reflow of U7000, now 3v3_G3H is @ 3v42 with enable pin @ 5v0 (fed by U7000). 2) the above is good but now the power is cycling every 3-5 seconds on this power rail (ON/OFF). The external Type C in-line meter goes black and then power cycles again. Believe that we are drawing...

Hi. This nightmare continues... 1) replaced U7000 - oh what fun this was 2) replaced D6902 BAT30CW dual diode as +5v0 was not passing through from anode to cathode. After replacement, Pin 3 (cathode) on diode = +5v0. 3) External USB meter shows 5v0 @ 0 Amp like the other thread on this forum...

Thank you again! Was concerned about the "off value" for this area and did exactly as you suggested, removed the high side resistor and it indeed does measure around 750K (as per the schematic) and the south side as per the schematic. The in-circuit value was throwing off the reading. Sorry for...

Thanks @2informaticos for your prompt comments. Will work on the replacement of U7000 today. A few more questions: 1) Can you comment on F7000? Is that a one-time fuse or a polymer (resettable) fuse? The original is in tact but wish to know if it can be replaced and with which part number (if...

Hi. Been at this Macbook Pro repair for a while. The unit just decided to not power up one day so it was brought in to us for repair. Tested with a Type C PD tester and an external power supply which originally dialed up 20V contract but the current draw was very low (close to 0 mA). After...
