    Hi guys, i have a problem with board 820-00239-A (no liquid damage). In short was U8000. After change still no power on but charging. I try change U7800 but still doesn't work. Here is all result:

    PPBUS_G3H - 13,05V
    PP3V0_G3H - 3,078V
    PP3V3_S0 - 0V
    PP3V3_G3H - 3,404V
    PP3V3_SUS - 3,352V
    PP3V3_S5 - 3,354V
    SMC_DELAYED_PWRGD - 0V
    CPU_VCCST_PWRGD - 0V
    SMC_ONOFF_L - 3,4V
    RTC_RESET_L - 3V
    ALL_SYS_PWRGD - 0V
    S5_PWRGD - 3,265V
    PLT_RST_L - 0V
    PCH_INTRUDER_L - 3,078V
    PCH_SRTCRST_L - 3,057V
    PPVCCPRIMCORE_SUS_PCH - 1V
    PM_PCH_PWROK - 0V
    PM_PCH_SYS_PWROK - 0V
    PM_SLP_S5_L - 0V 100kO to GND (R1454)
    PM_PWRBTN_L 3,3V
    PM_RSMRST_L - 3,351V
    PM_BATLOW_L - 3,335V
    PM_DSW_PWRGD - 3,4V
    PM_SLP_SUS_L - 3,354V
    PM_SLP_S0_L - 3,352V
    PM_SLP_S3_L - 0V
    PM_SLP_S4_L - 0V
    PM_SLP_S5_L - 0V
    PM_SLP_S0S3_L - 0V

    PPBUS_HS_CPU - 13,04V
    PPBUS_HS_OTH5V - 13,04V
    PPBUS_HS_OTH3V3 - 13,04V
    PPBUS_S4_HS_TPAD - 13,05V
    PPBUS_PMIC - 13,06V
    PP5V_S5 - 5,01V
    P5VS4_PGOOD - 0V R7801 100kOhm and diode 0,425V
    S5_PWRGD - 0V, R7802 85,5kOhm and diode 0,456V

    After change U7650 S5_PWRGD is still 0V but now R7802 is 100kOhm.

    Any suggestions?

      MacBook Pro 13inch 2017mid (A1706 820-00923-A) - liquid damage - USBC and Display short circuit
      by rilley
      Hello everyone,
      I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.

      I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A

      My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.

      And the resistor L4004 is literally burned.

      From what I see from the schematics, it does not affect any other rails, only the connection to the display...

      How to clean Liquid Metal from under CPU?
      by silver60618
      Hi all, Im working on a board, that my customer brought to another shop, and smeared liquid metal all over the board.
      The laptop powers on, then shuts off. I noticed traces of Liquid Metal near the edge of the CPU, but I fear some maybe underneath.

      Has anyone ever tried Ultrasonic cleaning, or compressed air to remove or agitate the liquid metal?

      Strange liquid on damaged GTX1080 card
      by kurland
      Hi,

      I'm fixing a GPU card for a streamer, was sent to me by mail. A shorted cap on a power rail has severely burned the PCB.



      As you can see from the darkened PCB around the mosfets there are signs of liquid damage. But it's odd because the person says no water has entered the PC cabinet. If you spill something on a desktop you would know I guess...

      Funny thing is that the liquid is not only on the PCB but on top of many chips which are tightly covered by thermal padding under the heatsink, even on top of some of the RAM chips

      Liquid cooling?
      by Hondaman
      I hope my computer does not randomly reboot while typing this. My main system is the AsRock 970A-G/3.1 motherboard with the AMD 8150 chip. I am experiencing FREQUENT and RANDOM reboots once the system is used for a couple of hours (sometimes it reboots before I even get to the Win7/Linux Mint dual-boot screen). The problem MIGHT be the DRAM controller chip (I recently upgraded to the maximum 64 GB RAM). It also might be the VRM chips. I am using a typical aftermarket CPU cooler, which does NOT blow air DOWN onto the VRM heat sink.

      (After previous generation hardware [Gigabyte] didn't...

      A1706 no power, no liquid
      by harryw
      Hi,

      looking at a friend's dead MacBook Pro (A1706). Input voltage 20.41V with a current of 21mA.

      Upon visual inspection I noticed blown capacitor C6580 and verified that a short to ground exists.

      I am assuming this is the same cap as the ones nearby labelled NEB CN7, which I've tracked down to Mouser part number 80-T521B336M016ATE70

      Can anyone with a A1706 board confirm that C6580 is indeed labelled NEB CN7?

      Thanks & cheerio, Harry....
