    Asrock 4Core Dual-VSTA no power to USB,PS2

    Hey guys,

    got this mobo with no power to USB or PS2 Port.

    Temporary solution is a PCI to USB card.

    but i am eager to find the problem as this mobo worked until 2 days ago.

    i couldn't find even one fuse on this entire board!

    im afraid that the windbond chip failed-(didn't check it with scope yet)

    what would you suggest?

    (the image is from google for now- as no visable damage such as burnt chips or bloated caps

      get a manual first.
      there will be jumpers to switch the ps2 and usb power from 5v to 5v-standby so you can power keyboards & stuff while it's turned off.

      you should check these, and the surface-mount polyfuse will be near them.

              lol I have this board, it's a good board, been using it for like 10+ years no problems. How do you know 5stdby or where to solder to? do you have schematics for it?

                  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...
                  ORIGINAL POWER SUPPLY BOARD

                  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...

                  Asrock H87-Pro4 Rev. G/A 1.04: Power cycling on reset only
                  by MyBrainIsAStrainer
                  Hi!

                  I have a weird one for you. I have a H87-Pro4 from Asrock that power cycles. But only when you do a restart after it was already running!

                  Symptoms in detail:
                  1. I switch off the ATX PSU for ~15-20 seconds, then switch it back on again.
                  2. I press power button. The board boots without issues.
                  3. I can shut down the board any way I want (via OS* menu, or pushing the power button - either in the OS or the boot manager).
                  4. Push power button again, board boots fine.
                  5. This shutdown/powerup can be repeated multiple times without problems.
                  6. BUT: If I do a restart instead
                  ...

                  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...
