    Vizio E421VO Screen Flashing

    Hello.

    I was given a Vizio E421VO that I am trying to troubleshoot. The issue it is having is that when it is powered up, the screen is flashing continuously with vertical lines. No sound from what I can tell. It powers on/off no problem. Before taking it apart and checking the MB and Power Supply, I thought I would check to see if anyone has encountered this problem. I was wondering if this is a panel issue before starting to take voltage measurements, etc.

    any information would be appreciated...Thanks!

    Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
    by HTR-Informatique
    Hello,

    YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

    I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

    On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

    I also changed the screen because the PC fell and the screen was broken.

    I changed the battery with a new and original battery.

    I also had corrosion/oxidation on the...

    Vizio TV M50-C1 reboot cycle and static on screen
    by spice_disc
    I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

    The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

    Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
    by Ryan.man
    Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

    My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

    This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

    Vizio m65-c1 picture flashing on and off on the screen
    by maricm
    HI all,
    hope someone point to the possible issue before I start buying replacement parts.
    Tv starts normal and responds to remote fine, PSU voltages mesured fine 19v was 18.9V under load and 19V with main board disconnected.
    Backlight stays on all the time,
    Sound works fine.
    screen keeps changing form black to full picture in about 1sec intervals.
    Picture looks fine with no visible artifacts.
    I have disconnected backlights and flashlight test confirmed that picture is still doing the same.


    Disconnecting left and right ribbons on...

    Vizio E55-D0 and it has a flashing screen
    by Megan0
    I have a Vizio E55-d0 and it has a flashing screen when I turn it on. I check Tco board, Main Power and everything was fine then I checked all the LED strips and found 2 bad LEDs. now I do not want to change all the strips because it is expensive for me, I just want to change these 2 bad LEDs (I know it may not be the right way but I want to try it) I just don't know what kind of LEDs should I order? Does anyone know to guide me. Thank You.
