    Well in the Tech Sheet I got for the LCD panels I tried to get going it says I should get a reading of about 300-500Volts (rms) ... the lamp frequency will be between 20-60 Khz ... as this is pulsed by the lamp supply ...

    Watch out for the Kick Off (turn on) voltage as that can be around 1000+ volts ...

    Your's should have similar values ...

    The 3.3volts is the power supply for the control board by the looks of it ... definitely not the lamp voltage ...

    The voltage will be AC ... as it comes straight off the high voltage transformer of the DC/AC converter lamp supply ...

    cheers,
    Gem
