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 picture.
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.
