    I have encountered an incident sometime ago. A pranked (i suspect) was played in this way

    1) on my smart hp - the screen is unable to move
    2) on the tv - the screen blur but the sound is there

    Is there such a possibility of a gadjet exit to change the signal of the electronic item(hp,tv, radio, camera..etc). If that is so, could there be a possiblity that this gadjet be remove, stop or detectable?
