    Acer AL732 - 2 secs. to black

    This monitor uses a separate power brick to provide 12V input

    Turned On using its power button, the display shows an Acer logo followed by a quick glimpse of which input it's scanning, before going black again

    Although the power button will stay lit until pressed Off again

    So I disassembled it, hoping for obvious bad capacitors somewhere

    No such luck

    The board pictured is where 12V comes in, along with video & audio inputs, but seems faultless to my inexperienced eye

    Except that its caps are all Suscon

    Am I barking up the wrong tree here, or are Suscon on this board likely to be the root of the problem?

    better to keep quiet and be thought a fool, than to open your mouth and remove all doubt

    if this is a ccfl set i would start by checking the inverter transformer then maybe test the ccfl tubes
