That does not sound right at all, you should have in the DC secondary circuits: 12vdc at the DC filter caps (rated at 25vdc) section, and 5vdc on the filter caps (rated at 10vdc). The power supplies are always running, even when the monitor is OFF but still plugged into the wall.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.
