    Post Schematics/Components needed for backlight inverter

    Hi
    I have the Sharp 6" LQN6C02 but as being in Australia I have unable to find a decent backlight inverter for the two CCFT's of the backlight.
    I have broken fluro tubes just to get the inverters out of them but they seem to only be able to supply enough power to power one backlight not both.
    Their PCBs look really simple with a transformer, capacitor, resistor and some regulator.
    I was wondering if anyone knew of a diagram or how to build a backlight inverter?

    The backlights specs are.
    typical voltage - 330V (290Vmin - 370Vmax)
    typ. current - 7mA (6mA min - 8mA max)
    and 20 - 50hz frequency
    power consumption is 4.6 - 6W

    thanks for any help!
