    A1708 No Power

    PPBUS_G3H Present
    PPDCIN_G3H Present
    PP3v3 G3H Present

    Tested Rails near SMC, Present

    20Volts SO USB C is good. Replaced a few caps injected voltage in some lines still can not find the short. I am lost here. I am certain it is the S5 S4 or S3 rails because they do not have power.

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      Microsoft Surface Pro (5th gen) model 1796 - no power
      by PantherDave
      Hi all!

      I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

      I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

      Asus Probook P5440UF-XB74 power issue
      by GLISIT
      Hi all,

      TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


      I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

      A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

      Dell Latitude 7390 - all power rails up except VCC_GT, no image.
      by kitor
      Hello,

      I have Dell 7390, LA-F311P.

      AFAIK there's no schematics available, but there's one for LA-F312P in this thread. It differs in no Thunderbolt controller (iirc that's for 5290/5390), however rest of the schematics/BV seems to match 1:1.

      Behavior:

      Connected barrel plug, no RAM:
      - power LED turns on + orange light on front
      - turns off after a second or two

      Connected barrel plug, with RAM:
      - power led turns on + while light on front
      - after a few seconds power led turns off, white light...

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
