Power light blinking? Try Plugging directly into the wall outlet istead of the UPS?
Otherwise you may have problem in the power/inverter board and need to do component level troubleshooting.
If you are going to DIY and have proper tools and know safety precaution then please read on:
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 DELL 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.

Check F9A04 and F9A05 on the center ( Power) Board if those fuses are open the Convergence ICs have failed.

check the bulb door and make sure its closed all the way. be sure the bulb is firmly pushed into its socket. if the problem is still there you may need to repair the power supply board.

vscan is a voltage used to setup the picture for the panal. It goes to the y sus board. The problem is at the power supply or the y sus board. You can check these with a meter.

Remove the stand by removing the screws at the center back.
pry the front and back plastic apart with a large flat blade screwdriver. The front and back snap together so you need to "pop" them apart.
