The power supply has failed, or there is a short on one of the boards loading the supply. These types of monitors and TV sets are serviced by board swapping. If you have a lot of service experience and the test gear, if the problem is simple you may be able to find it with conventional troubleshooting.

In this case, no test equipment was needed - the pictures on the linked page show the electrolytics have swollen ends. This was probably a "save 2 cents" design-related failure, where the capacitors are running right at their 16 volt rating. Replacing them (with 35V caps) restored "like new" operation.
