    Mac A1278 J30 820-3115B

    I'm trying to repair this beer damaged board and I've got 17.x volts up to the U6990. On the U6990, I only have power on PIN 7. Is the U6990 the first thing I should replace?

      PS5 digital / No Power / No Beep / Good power supply
      by MisterAIL
      Hi everyone,

      Brought a non functionnal PS5. Apparently only a bad PSU...
      No beep, nothing.

      After some tests i found this :
      - PSU is fine (12 volts stable)
      - 12 volts line is shorted
      - DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
      - By the way, nothing change. No signal, no power, no beep.

      Mesuring all rails with my workbench psu (12 volts input)
      - 0.00 amp drawing
      - 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...

      Dead Dell Latitude 5420 not receiving 20 volts from USB-C charger
      by BTubbs200
      Hello,

      Dell Latitude 5420 P137G
      Board: LA-K491P REV A01

      I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

      Board seems to have no shorts, all power rails are fine and show high resistance.

      When charger is plugged in, voltage is present in 3.3V rail but absent in others....

      MPJA 10 AMP @ 0 to 30 Volts Switching Power Supply Cap Fault
      by sam_sam_sam
      I have this 10 amp 0 to 30 volt switching power supply that decided to have a 630 milliamperes draw on it at 0 volts

      I open it up to find non brands name capacitors in it

      I am not sure how this switching power supply is set up

      Could someone please explain how this power supply works

      Here is the capacitor ESR results

      (1) 47uf@50 volts 0.46
      (2) 47uf@50 volts 0.45
      New 47uf@50 volts 0.35

      (1) 100uf@25 volts 0.34
      (2) 100uf@25 volts 0.35
      New 120uf@50 volts 0.08

      MacBook A1278 (3115) No PPBUS_G3H Issue
      by pcbmaniac
      Subject: Help Needed: MacBook A1278 (3115) No PPBUS_G3H Issue

      Hello everyone,

      I'm working on a MacBook A1278 with the 3115 logic board and facing an issue with no PPBUS_G3H voltage. Here's what I've checked so far:
      1. U7000 Measurements:
        • Pin 3 has 0V, even though R7012 shows 16.5V from PPDCIN_S5_CHGR.
      2. Resistors:
        • I measured R7010 and R7011 with one leg disconnected, and both tested OK.

      Based on these findings, I believe U7000 needs to be replaced. However, I have a related question:
      • If I also decide to replace the SMC, do I need to order it pre-programmed,
      ...

      I am looking for a transformer secondary of 60 volts @ 30 amp
      by sam_sam_sam
      The primary voltage is 480 single phase the second voltage needed is 60 volts

      Now it could be 30 volts 0 volts 30 volts preferred

      Or it could be 60 volts 0 volts 60 volts and just use one side of

      Output amp need to be at least 30

      Dose anyone know where I can find one

      This is what is the device I am working on

      The problem with this one is that it is over heating and smelling like it is over heating

      When it has a load on it...
