    Toshiba 49U6763DG

    Hi,

    Need dump for this display:

    VES490QNDS-2D-U11

    Set boots fine, I have sound and back ligth, but no image.
    12vdc are present on the lcd bonded boards.

    Main board is: 17MB120 with both U11 and U13.
    I have Minipro TL866 (and others) to program the 25L1606 flash ic´s

    Regards

    you dont need to program the SPI Flash separate.. just run update or complete firmware again it will write the video & Panel driver again.

    Arizan Nothari web page had all what you need.

      But dont have any image on LCD...
      And also no files needed to update.

      Now I do (thanks)....but I will make a backup of both IC´s before usb update.

        Take a picture of the tcon/board bonded to the screen.

        You may have 12v but let's see what other test points are there. Since you still have sound and the tv functions as normal I'd doubt that the motherboard is faulty at this time.

          Look for test points.

          AVDD
          VGL
          VONE
          VOFFE
          VGH
          V3.3

          IF you see any of the above post what voltage you have
