    Vizio V705-G1 Flickering

    Just picked this one up, the screen flickers as in this video. I will take some measurement tomorrow. Thought somebody might have seen this one before. It kinda looks like some arcing by where the backlight wires go through to the front. I cut the loom open as far as I can get but don't see anything obvious. Here is link to screen flickering. https://youtu.be/cJRi7v0ypn8

      Must of the plugs are dual rows, I guess it’s best to check from the back? Since I cut the loom open it now just starts up and turns back off in about 3 seconds. Looks like I need to remove screen to see the rest of that harness.

          That model likely uses local dimming so the LED strips are controlled row by row. What happens when you turn off local dimming? I have seen on one Vizio with local dimming that one bad LED in the strip will cause the entire strip to go out.

                  Well reseated some cables and moved the backlight cable around some and it seems to be working fine now. I did order a backlight cable to replace that one and when I pull the screen will check all leds at that time.

                      Did you ever get a resolution on this? Was it the backlight/LED cabling? Mine is doing the exact same thing as the youtube video.

                          Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
                          by howardc64
                          Problem

                          Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video

                          Conflicting Spec

                          Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

                          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.

                          ACER BM320 Monitor - Horizonal Flickering Lines After a While
                          by reessi
                          Hello,

                          The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

                          They are black on the right and gradually fade to nothing on the far left.
                          They start either after 5 mins or up to 2 hours after so annoying for testing.
                          They flicker continuously very fast! With a slight pause milli-second every second.

                          Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

                          I tested each half by removing the first the left flex from...

                          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...
