        Trying to work out which chip was driving the blown Mosfet. What IC number is on IC2.

          maybe a picture of the bottom of the board showing the area around where the blown moset is removed from will help us more to locate any other parts to check or change.

            I realized after I removed them to test I mixed them up so I wasn't sure which was actually bad but I think it was the one closer to the diode.

              I think the Mosfet circled in Blue was the bad one.

                Hello everyone !
                Thanks for all your help !
                I found a power supply board for like $42 w/ shipping.
                It came today and after installing it I now have a working TV again.
                I may look around for the power mosfet and replace it and the fuse to see if it fixes the bad one or I may just hang onto it for parts.
                Thanks again everyone for your help !

                  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...

                  by WVUfan
                  hello. i've a ps5 edm-033 mobo w/ no power, lights, but one beep when power pressed. i've hooked to uArt and only error code is 80871001 (DDR4 No Power or Short Circuit). i have a donor board, same model, that does power up, fan spins, blue light, and beeps 3 times, then powers off. it has a botched HDMI port replacement job. so w/ the board i'm interested in, with the error 80871001, i was able to research and obtain voltages of the SSD PMIC. i've attached pictures of the provided diagram by DylanBBK (@d62 on Discord) and my voltages and picture of my board. my question is on my picture...

                  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...

                  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...
