  1. I just got this Sony SDM-HS73 LCD monitor and the person told me that it
    wouldn't power on. I plugged it in and it worked.. Then I used it for a
    while and it went in to power save and wouldn't come out of power save...

    You could cycle the power with the vga cable unplugged and it would say on
    the screen no signal. If you plugged in the vga cable it wouldn't display a

    Now it won't power up at all. You can hear the filter cap charge up and
    thats about it. I guess what I'm asking is do you think the problem is in
    the controler board instead or the power supply?

    I'm going to get the service manual since this monitor is a bit different
    than any lcd I've ever worked on before. It has the power supply
    intergrated into the inverter.
