    Cartoons looks good but other channels show it a lot more.

      Out of curiosity, what would happen if I took the other side drivers off?

        You would have nothing but vertical bars as the panel will dots be able to gate drive the information from the source drivers anymore
        Did I leave the soldering iron on?

          Pull the right T con ribbon. Let the left side only run. Do you see any dark areas on the left side of the panel? Also on the right side it will be white does that look dark in the center?

            Makes sense lol. Just wondering. Im about to give up hope. Someone suggested earlier to disconnect the tcon board on that side but I never found out why.

              Re: 70in Vizio m70-c3 replaced led's now picture screwed up.

              Doing it now. Should I pull both on the right side and just leave the 2 on the left connected?

                Never mind. You mean on top of the board? Thwres 2 black ones. Pull the one on the right?

                  There was no picture. Only sound.

                    That's what I pulled, hope it was correct.

                      you need to pull the one for the same side that the tabs were removed. If you pull the one for the other that doesn't have the side tabs removed, you will get no picture.... since no signal will be delivered to any sides. you should see half a screen with some picture and half that is white.

                              You pulled one of the two LVDS cables between the main board and the T-CON board, not the cables (4 white flat cables) between the LCD panel and the T-CON board, that is why you do not get the pictures.

                                Ok. I was wondering if I pulled the right one or not. Figured I didn't. Will pull the 2 when I get home from work. Honestly about to see if a sledge hammer will fix the problem...

                                  Ok. So here's the pic after right side tcon ribbons pulled. Is there anything else that I can try? Would love to keep the TV but its driving me crazy lol. I'm a "work on it till its fixed or till its dead type of guy". So I'll try anything.

                                    Does the left side still display the dark spots with righty disconnected ?
                                    Did I leave the soldering iron on?

                                      I would look over the areas where u removed the tabs very closely (magnifying glass). U may have shorted line. otherwise your going to have to live with pic

                                        Yeah, there's still some shadowing there. I honestly think the suction cups were the problem. Which pisses me off. I will not use them on a panel again.

                                          you never really answered the question as to whether the suction cups had "valving" for releasing air / vacuum? Also, how did you actually apply them... blaming them for this might not solve any future issue if it was "operator error", regardless of what cup system you used.

                                            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...

                                            Hi there !

                                            I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
                                            Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...

                                            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...

                                            Vizio SmartCast TV software bug that looks like hardware
                                            by howardc64
                                            Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.



                                            It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot....
