    Vizio 65 LCD grey vertical bars

    hi

    i have a Vizio 65 LCD that has great picture but has 4 vertical grey bars on the right half of the screen...

    they do not change..i tried swapping the ribbon cables..no change

    if i tap on the tcon board or tap on the bonded panel tabs the bars stay the same

    this makes me think it could be tcon issue or bad panel

    any input?

        Does anyone know if this could possibly be a main board video processing issue or should i assume its a lcd panel problem?

          panel had damage, actually the damage could be visible if you remove the screen bezel

            Yes i removed bezel earlier..and..I found issue...4 of the ribbon cables to panel were torn....poor design...where its bonded it got cut on the sharp edge of the lcd panel...and tabs are on bottom of panel not top...which doesnt help...if it was on top it would happen since the gravity pushes panel away from ribbon cable...

            Tv will be tossed in trash

            You can thank the cheap poor design of lcd tvs for helping landfills getting bigger

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

                    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...

                    Samsung UN46C8000XFXZA vertical bars/horizontal lines
                    by x_orange90_x
                    I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

                    The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...

                    Vizio E70-E3 Two white vertical lines
                    by brad2157
                    I picked up a Vizio E70-E3 for free that shows Vizio logo and then goes to a black screen. Original owner said he started having wifi issues and then he tried to reset the TV and that's when it wouldn't boot up any longer after his reset attempt. I picked up a replacement main board from eBay that matches the same model # board as the original from the TV.

                    Original main board - Shows Vizio logo when TV powers on, then goes to black screen. Doesn't boot up. No screen issues with any lines on start up Vizio logo.

                    Replacement main board - Boots up fine, but starting...

                    Sharp LC-70LE650U vertical black and red bars
                    by ninja_zx11
                    Hi all,

                    70" LED TV is Sharp LC-70LE650U.

                    Initial problem was horizontal lines and slow motion lurrs on the bottom left of the screen. So I removed both the left and right ribbon cables from the T-con board and tried to clean it with alcohol and when I put it back, this issue appeared. I tried carefully reinserting the ribbon bon cables but same thing. I checked the traces of the ribbon cables with magnifying glass and everything looks good. I cleaned the small jumper ribbon cable on the left side of the screen which cured the horizontal line and slow motion blurs...

                    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...
