    Veiwsonic VX910 LCD monitor

    If anybody has these schematics or nows of them on line I am trying to find
    the part number for D660 on the power board. I've had a few suggestions and
    I appreciate it but I'm still stuck.
    If worse comes to worse I could try a suitable part (believe to be a dual
    diode) if anybody has any suggestions on a replacement.
    If she blows she blows, oh well.

    Thanks people

    Can you upload a photo of the PCB to your web space?

    I don't have any webspace but I could email you a pic of it. I have the pcb
    out of the monitor.

    Replace the caps that are around D660. thats what was wrong with the
    one i have on my bench. (2) 470ufd at 25v...also there is a 330ufd
    cap
    wrapped in a sleeve not far from that..replace it...as far as your
    diode,
    if you can find the original, NTE lists a replacement for MBR20100CT.
    Not sure if its the same, but might be worth a shot.

    I went and ordered the diode from my local electronics shop but its going to
    take over a week to get it. Thanks for the tip about the caps too. I will
    probably do them as well.

    Thanks
