    Vizio SV420M green vertical lines

    It's been a while, since I have posted here.
    I have got this TV, from a coworker for free and I'm trying to repair it.
    I have replaced the T-Con board, since it was a couple of bucks, but nothing changed.
    I'm measuring the voltages and they are all there.
    Removed ribbon cables, re-inserted them again, with no change.
    Any ideas, what else can I try?

      I'd change the main board.

          I suspect the mainboard as well, but it is not available, or it is over $100 which is not worth it.
          Do you think, that it would be a bad/old capacitor?

                  i doubt it, but you could easily find out by heating up the caps. just for heck... flex or squeeze the frame a little

                      Didn't try different sources. You are thinking analog source?

                              I have tried only HDMI 4. The menu has the same issue as well.

                                  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...

                                  by viking509
                                  I recently replaced the led backlights with LB65041 LED Backlight Strips and after putting it back together the backlights work but there are only colored vertical lines only in the center of the tv. I can see the Netflix logo (jumbled) after a minute or less the screen went dark. When I turned it on again the lines were back. Then I replaced the t-con board but the same vertical lines in the picture. My question is what is my next step? Could it be a source tab bond issue? A buffer board issue? Could I have loosened a connection to the panel when replacing the backlights? Should I replace the...

                                  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.

                                  Samsung LA46A950 aka. LN46A950 - intermittent vertical green lines / distortions
                                  by 265chemic
                                  Hi All,

                                  I have a Samsung LA46A950 that intermittently was displaying issues with evenly spaced vertical green lines only on dark / black areas - this has progressed to more often and blue lines sometimes, as well as a little image distortion.

                                  My initial suspicion was the T-CON board, which I took out and cleaned but the issue persists. A heat gun on all of the control boards makes no noticeable change. Ive also reseated the T-CON to panel ribbons (4 of them) and moving them while the panel is on doesn't seem to change the issue.

                                  Below are some photos...

                                  Colorful LCD Vertical Lines on Samsung ue55es8090
                                  by Falki
                                  Hello there, ive recently found an older 55inch Samsung SmartTV.
                                  Sadly it has vertical lines at the left and one line in the middle-right.

                                  I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
                                  I have factory resetted the TV as well but also with no luck.

                                  I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

                                  A similar issue has been posted as well but also with no actual response ...
