          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.

          troubleshooting microsoft surface pro 4 no power no led charge light
          by ipatch
          hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

          iPad A2197 no power, A10 and other IC become warm, only 0.5A charge
          by proxneo
          Dear reader

          TL;DR: iPad not turning on, A10 and power IC become (very) warm when attempted to turn on but this power-on cycle has a 'cooldown' period wherein powering on doesn't work, does not take more than 0.5A charge.

          I am working on an iPad 7th generation 2197 from >2019 with no / limited charging and no boot issues. It is a refurbished purchase made in 2021. It appears the 'refurbish' company has either done prior motherboard work (all protective component shield layers are gone) or is one of the many trash refurbish companies (little screen adhesive left, component...

          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...
