    Vizio M65-C1 intermittent half screen outage

    I have a Vizio M65-C1 that intermittently loses the video on half of the screen (see pic). When first turned on, the TV works fine, but after a while the right half of the screen becomes a flickering, jumbled mess of lines. After a bit the TV usually restarts and works fine for a bit longer. I'm wondering whether anyone can tell me if the problem is the Main Board or the T-Con (?). A clue is that the main board heat sink becomes very, very hot. The two large ICs on the T-Con get pretty warm, but not alarmingly so. Thanks.

      This is a a signature main board issue. Common failure for these main boards. We see this with the P502ui-B1 P552ui-B2 P652ui-B2 often as well.

              Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
              by howardc64
              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 E70-E3 Half picture with half TCON
              by Fly_Among_Stars
              Hi,
              I have a VIZIO E70-E3.
              Symptoms: Black screen, no picture, but LED backlights are working.
              I probed the power board and voltages are as listed on the board.
              Main board appears fine, too.
              I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
              There are two separate ribbon cables feeding the LCD.
              If both are connected, the screen is black.

              If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

              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...
