    Re: Vizio E3D420VX No picture, Power light blinks on then no power

    FIXED!!!

    I spent $32 on a new power supply board from Shop Jimmy and it worked! And while I'd love to know which specific component on that board failed , I'm pretty stoked. I got this TV free from a friend who didn't want it when it quit working. Vizio didn't want to pay to fix it so they just refunded him his money.

    WOO HOO!!!

        Hi! I have a symptom in Vizio E3D420VX TV
        1. Press power button, power white light on and Vizio V logo is on the screen
        2. Logo goes off, power white light blink one time.
        3. Power goes off by itself and doesn't come up
        4. Same symptom in every time when I press power button.

        Is it an exactly same symptom as you?
        Can it be solved by replacing the power board?

            Or, do I have to replace the main board???

                My problem was different. For me, only the white power LED blinked for a few seconds and then turned off. The screen never showed anything.

                    Hey everyone, I replaced the power supply board as suggested, but that didn't fix my issue. What should I do next?

                    This sounds like my issue. So far, a new power board hasn't solved the problem.

                        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.

                        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...

                        Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
                        by Alicat
                        Hello,

                        Stopped by this site trying to fix my parents Panasonic Plasma TV.

                        Model number is TH-50PZ85U

                        Power comes on and the red power light stays on solid.

                        Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

                        I also hear a few clicks.

                        I also think my parents said there was a thunderstorm and the TV failed after that.

                        Section 6 in the service manual talks about power and no screen,...

                        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...

                        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...
