    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...

    Vizio VO42L Issues: Need Guidance
    by ChillingCicada
    We've had our Vizio VO42L since before 2010, and it's worked flawlessly this entire time. However, just recently it started emitting a high-pitched buzzing/humming sound. I followed the basic troubleshooting tips of just unplugging it for a moment, and even holding down the power button while doing so, all to no avail.

    Furthermore, after I attempted these basic steps and powered the TV back on it would always begin visually flickering while the sound stuttered. After a few moments of being turned on this would go away, but it still periodically comes back.

    I also...

    Where to find a very small fpc connector 0.3mm between 2 pins ?
    by corrize
    Hello, I search this connector (oxydated).
    It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
    I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
    I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?


    Do you know how to find this connector please ? What is the exact name for find it ?

    Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
    by howardc64
    Failure Symptom



    No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

    Where is the short?

    Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



    Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...
