    I have a nice sony 19' LCD screen (color )but it goes blank after
    almost a second after it has been switched on. It displays the image
    from the PC but after the said time the image can faintly be seen
    I'm suspecting the high voltage inverter but finding a replacement
    here in Ghana- W/A is a problem
    Can anyone tell me the problem if I'm wrong? or suggest a solution.
    May I also know the voltage to the tubes? (as I may try to build
    an improvise ) It has 2 tubes each with 3 leads. What does the 3rd
    lead do ? if not a ground wire.
    Thanks all good pals on
    this wave.
