    Hi People,

    I've search the net and this website and haven't found any thing about this topic, but maybe its just my ability to search.

    My iPhone isn't responding and I think its the logic board.
    Here are the reasons:

    When plugged to my car charger, the charger's light doesn't change. Which shows that the charger isn't recognizing the iPhone.

    When plugged into my computer, nothing happens.

    When the power button is pressed, the screen does not response.

    Even with a dead battery, the screen should show a charging icon when plugged into charger or computer. If screen does not work, the phone should turn on become warm. The phone stays cold.

    That is why I think its the logic board.
    What do you think?
