      They look OK, I figure you are assign pin 1 as input pin.

          Found it hard to trace back the K fuse to anywhere on board, such thin traces.

          Included a picture with the wires going to the standby led tiny board.

          Black wire 2.7v
          brown wire 5.0v
          red wire 3.2v
          orange wire 0.0v
          yellow wire 3.2v
          gray wire 0.6v

            Subscribing, since I have the same issue.

              Sounds like you have a bad eeprom on the main board.. I found them on ebay for $20 preprogrammed Hope this helps

                thanks! I'd posted a while back about one I had (have) that I recieved after it's owner had removed all of the caps and I didn't have any clue about what they needed to be. Now I can finally move ahead with that little project I have had sitting behind my file box! I can just match them up on the images vs the repair kit list.

                  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...

                  Vizio E550i-A0 no power, no standby light
                  by x_orange90_x
                  I have a Vizio E550i-A0 that will not power on. It also does not display the standby light in the corner. I disconnected the main board cable to see if the backlights would light but they did not (maybe this is normal for this set?). I checked the voltages on the plug and they all read in mV or 0, so there's no voltage there. The fuses are ok, and the voltages of the 450v caps read about 160v. I see no visual damage on either the power supply or main board. I have read online that the main board is usually the culprit in this model, but not getting backlights with the main disconnected makes me...

                  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...

                  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...
