    MSI GT70 Issues After Power Jack Repair

    I have an MSI GT70 laptop which came to me for repair with a faulty power jack. When I dissassembled the unit I found the jack was completely burned out on the positive leg and had fused together with the positive and negative inside the motherboard (checked with multimeter).
    I was able to disconnect the filters from the main power input and remove the short between positive and negative by jumpering a new power jack directly to a good area of the board. This was working fine and the machine turned on, charged the battery etc. Unfortunately this has now stopped working and the machine no longer powers up - i've checked the power going into the board is still correct at 19v when the charger is connected and i've got 3v at the power button.

    Anyone have any suggestions on what to check?

      hi bro,
      check if there is missing coil or capacitor for emi, try to find schematic diagram to check properly the missing part.

          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...

          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...

          Original NES power issues
          by sli4
          I recently turned on my old NES to find the red light won't go on at all. When powered on it shows black bars on the tv and a loud buzz through the tv speakers. Powering it off, the buzz goes away and tv goes back to normal (white snow).

          I tested the power supply itself and it is outputting 9V as it should - first two solder joints on the board at the power port show the same.

          Here's where it starts getting funky - When powered on, one side of the 7805 voltage regulator is showing 18V and the other is about 8.7V (center 0).

          On the big blue connector I get...

          MSI Z370-A Pro, works but does not power off or reboot and USB issues
          by gretti
          I have a MSI Z370-A Pro. The board does not reboot or shut down from the Windows recovery console. USB communications stop and the status light on USB 1 stays on and does not blink. I have programmed a new BIOS with a CH341A programmer already, swapped RAM, PSU, CPU. The board will power off when the power button is held and resets when the reset switch is pressed, but it will not react to the reset switch if already told by software to shut down or restart. The board will reboot from BIOS after a save and exit command.

          The MSI BIOS included the ME firmware for the board. The size...

          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...
