    Samsung UA55HU7000 TV: HAVDD missing

    I am working with a Samsung UA55HU7000 TV and backlight and sound works (volume up and down sound checked). But no picture. T-Con was replaced with a new one and still the result is same. Even with the old T-Con and new T-Con found that some voltages are missing. I feel the heat of main IC of the T-Con.

    HAVDD: 0V
    AVDD: 0V
    VCC3.3: 3.3V
    VCC 1.15: 1.1V

    What can be further investigates. Appreciate any support.

      Samsung UE65TU7172 – BN41-02751C – CI+ ECP Keys Missing / Digi Card Not Working
      by nader_guesmi
      Hey everyone,

      I’m working on a Samsung UE65TU7172 with mainboard BN41-02751C. The TV powers on normally, I’ve applied the latest software update, and all measured voltages are correct.

      Problem: The CI+ module doesn’t read the Digi card.

      I accessed the service menu (using Mute + 2 + 4 + 7 + Exit) and ran the CI+ test. The results show:
      • CI+ production keys: Success
      • ECP keys: Not installed

      So the TV doesn’t even attempt to communicate with the CAM/card.

      I’ve tried multiple Digi cards (both old and new), and they work fine on another...
