    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.
