Though some TVs now come with a two pin IEC connector only...

  Just asking due to curiosity: Do modern TVs need high voltage circuits unless they're plasmas? Also, are there any standards which force internal bleeding if there's no earth connection?

    I'm not sure about the other one, but: >Do modern TVs need high voltage circuits unless they're plasmas? The way a lot of power supplies work, is that they rectify the 110V/230V to a reasonably high DC value, and change that to a high frequency AC signal so it can be transformed to a lower voltage with a smaller transformer. This means there's typically some capacitors charged with sqrt(2) * line voltage during normal operation.
