    NS-43DR620NA18 picture jumps vertically

    43" 4k roku insignia

    Was told this tv had a flickering issue, so I assumed backlight--power board and pulled the back off to examine before firing it up.

    Instead, I see that it's not holding the picture vertically. Backlight is completely fine.

    Here's a video (sorry about the rotation): https://youtu.be/7YY8NafwNGI

    Could this be a tcon? I've reseated the ribbons / applied pressure to the tabs.

    tcon appears to be ts-5543t10c03 https://www.shopjimmy.com/vizio-55-4...3-e2-lwz2vnbt/
    mainboard 715G8501-M01-B00-005T

    edit: unplugged the right ribbon, and the left picture is perfect. Then, as expected, plugging only the right ribbon results in a jumping right picture. Is this indicative of a bad tcon board? Will try the tape method now

      Upon further research, it seems like the tcon is likely fine, and the tape fix may be the only economical solution.

          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...

          Samsung LCD TV no picture backlight on no 12v at tcon
          by shelby5041
          hi
          i have a samsung lcd tv

          it powers on with sound and backlight but no picture

          all voltages from PS are good 12v 3.3v and 5v

          whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

          i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

          no 12v at the tcon fuse

          i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

          the odds of having 2...

          TCL 50S535 bad tcon or panel issue?
          by x_orange90_x
          Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

          T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
          by Tr0ll
          Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

          The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

          Original T-con:
          Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

          First replacement T-con:

          I thought it might be t-con and ordered new t-con from china(supposedly tested)...

          Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
          by TR103
          Hi, I have a Samsung UE50TU with:
          - sound and backlight, but no picture
          - when it arrived, it had a picture for a few seconds
          - it keeps rebooting
          - without ribbon cable between the two panel boards, it does not reboot but I have no picture
          - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
          - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

          - without cable between mainboard and lcd panel and with a jumpered...
