The power supply section may be failed, or there may be a short on one of the boards causing the monitor to cycle through the protect mode.

If u a tech, try checking the PSU of the monitor for blown fuse or dead driver element ( typically a FET, Power transistor or an Hybrid chip) . U need to take the monitor apart, if unfamiliar, get it to a service tech.

This is the common bad capacitor problem. The caps have died inside, and they can be replaced. If you have basic electronics skills, you can go in, order replacement caps, and unsolder and resolder. If you can't do it yourself, you can take it into a shop.
Here is a link to the Cap plague that explains what happens in detail. But I repair these all the time with that symptom.

You have to install the nec driver for this monitor. I have the same monitor. Im looking for the driver now. There are 2 versions of this monitor with the same model # . You will need to find the driver to the touchscreen model.
