    Vizio VW26L-No power

    I got a Vizio VW26L from my brother and the original problem was a Gray/White screen no image no sound. Pressing the power button on/off several times got the thing to function. It finally gave out a couple weeks later, No signs of power when plugged in. I pulled the PS board and found a couple of bad caps. Because i repair old stereos i have most of the caps on hand. Im going to replace the 3 2200uf/10v, 2-1000uf/25v, 3 1000uf/35v and the 100uf/50v caps on the board. I have included a couple of photos. Should i be looking at something else as well-Didn't see any fuses.
    If anyone has schematics or voltages and test points it would be helpful.

    Well, make sure the caps are low ESR type 105c rating not general purpose caps, since they may or may not work properly in switching power supply circuits.

    I use PANASONIC FM or FR or FC series from Digikey.

          1. Remove bad capacitors.
          2. Install good capacitors.

          Done.

            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.
