Electromagnetic field and LCD-TVs

  1. Apr 3, 2008 #1
    Can a medium tension electromagnetic field cause permanent damage to LCD tvs?

    I am about to buy a LCD to my living room, but the builder said that, because of the electric cables in the wall having medium tension, it could cause an electric field that can ruin a LCD screen. Is this true?

    If so, how far must I place de TV?

    Thank you

    No magnetic fields do not effect an LCD in the same way as a CRT.
    Having said that, it is possible that electrical interference from other applicances could add noise to the signal circuitry in the TV.
    This tends to be more of a problem from noisy electrical motors in things like fridges rather than power cables in the wall.
