    Macbook Pro (820-2773) 20 ohm partial short on the pp3v8 power rail after water damage

    water damage to the left speaker channel circuit caused an internal board short that has been carved out and damage to various capacitors. I removed both chips ur630 and ur600 both were burnt. Im not sure how to track down this partial short. Any suggestions would be greatly appreciated.

    The fuse is blown on ppbus and im getting 12.24v to the ppvbatt side of the fuse

      MacBook Air M4 A3240 Brand New Water Damage no Image
      by Ugur87
      I have a brand new 13.6-inch MacBook Air M4 that was only used for three days and now has water damage. A glass of water was spilled over it. I examined the motherboard and there was only water next to the display connector. I cleaned it with isopropanol and the components look clean. The MacBook obviously turns on and draws 20 volts from the power supply. The keyboard backlight comes on, but the display remains black. Where should I best start? Even when I shine a light on the display, I don't see any image. I have all the tools I need, including an infrared camera. Where should I best start?...

      Stagg sms12p audio amp has water damage
      by edugimeno
      Hi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
      I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
      There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
      There is only one signal wire connecting the first boards...

      A2485, A2780(820-02100, 820-02890) PP3V8 short
      by JxxK
      Hello
      I am repairing the A2780 (M2Pro 16").
      There is no schematics and board view of A2708 yet, so I am referring 820-02100 (A2485).

      Stuck 5.2V, 0.02A
      'PP3V8_AON' short on diode mode and no voltage.
      'PP3V8_AON_MPMU' short on diode mode.
      'PPBUS_AON' looks fine. 12.3V
      'PPVIN_P3V8AON' looks fine(not short on diode mode), 12.3V

      I tried to remove the U5700, Q5800, Q5820, Q5840 and PP3V8 aond still stuck.

      It seems to be a problem in the process of moving from 'PPBUS_AON' to 'PP3V8_AON'.
      Even if I check with thermal...

      Macbook Air A3114 5V 0.0A after water damage
      by s_henya
      Hi Mac experts :-)

      Im usually not getting too many Mac logic boards repairs, (mostly PC laptops)
      This Mac isn't powering on not boosting to 20v, stays at 5v with 0.0Amps.

      Took out the board and it suffered some water damage, see attached pics.
      All cleaned with IPA but due to long time with corrosion something already got shorted...

      any advice on the below:?

      1. Looking for relatively safe location for voltage injection as all of the caps around that area has 0.0ohms resistance.

      I tried injecting 0.5v on one of the caps...
