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.
