The power to my Princeton VL193 monitor will go off after a few minutes. The power button light is also off. If I unplug the monitor for a while, I can plug it back in and it will sometimes come back on, but then go out again after a few minutes. If I leave it plugged in, it does not come back on at all.
SOURCE: i have the princeton VL193 monitor. Its blank, no power light
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Princeton monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Testimonial: "thank you the explanation sounds like its right on the mark. Unfortunately, I see these being sold used for under $50 so it is not worthwhile for me to repair as I don't have the expertise and I would think I would be charged at least that by a shop.I was hoping there was a reset button as I think the monitor succumb to an outage. Thanks again. "
