    element project elefs403s won't power up

    howdy all,I have a element led that I can't find the problem with it powering up and was wondering if anyone knows of any issues with this model before I really start digging into it.I can only think it's a cap or the chip isn't telling the PSU to turn on.I added a pic of the PSU.Thx for any help or input.

        How about good clear pictures of the whole back side of the TV so we can see how all the boards are connected together? and pictures of each boards.

            OK, this not going to be easy, this TV uses all in one power supply/LED driver/MAIN board combo, the LVDS from main board is fed to the 120HZ frame converter board, the output of the frame converter is then fed to the T-CON board.
            I cannot see any test point on the combo board to see where the PS-ON, BL-ON, etc. are.

                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...

                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...
