    Hi all,

    having an IPAQ 4150 with a defect backlight only, I wonder
    if there is a schematic flowing around. I would like to
    see if there is a inverter for backlight that could maybe
    being damaged.

    Any Help would be appreciated.
    Best Regards
    Markus

    You don't need a schematic to determine if the inverter is working.
    Measure the output to the CCFL or EL. CCFLs in these appliances
    typically have strike voltages around 300-400V.
