    Vizio D65u-D2 VIVID Setting = LED Shutdown

    Have a Vizio D65u-D2.. Works great as long as VIVID or VIVID-esque settings are not used..

    If VIVID is used, the LEDs shutdown after a couple minutes...

    Is this indicative of a bad LED strip(s) or a problem with the Main Board??

      You have to specify a little better what happens when it shuts down. Like does it still play audio just the back light turn off, or does everything just turn off?
      So monitor PSon and BLon with your DMM and see what happens.

      If the back lights just turn off on vivid, you can probably do the same in any other mode. You just have to crank up the back lights full tilt and wait. LED's can fail while they are stressed under full load, but still work fine when the power is reduced. May be a bit tricky to find, but worth to look at it.

          Yer right, I should have been more specific... Apologies..

          Yea, it's just the backlights that go out... I still have picture and sound... And you're also right, it's not just the VIVID setting. Any setting (GAME, COMPUTER, ETC) where the display is notably brighter, it happens.. This indicates an LED Strip issue...

          Another curious thing is that the power LED won't stay on, even though it's set in the menu to stay on all the time that the TV is on..

          That would seem to me to indicate a Main Board fault..

          I won't be able to get it on my bench until Tue..

          Thanx for the input....

              Did you fix this?

                  No I did not.. I explained to the customer he would have to keep the setting away from VIVID and he said that was good enough..

                  But I am still convinced that replacing a bad LED Strip would fix the issue..

                      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 M65-C1
                      by mrtek
                      Hi.

                      picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
                      When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
                      This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED...

                      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...

                      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....
