My computer monitor packaged with windows is not working?

Usually nowadays, my computer screen turns off by itself. I found that if I unplug the power cord and plug it back in, it turns on. Funny, but when it is on, i press the power button on the monitor, and it doesnt turn off. Same for when it is off, it doesnt turn on. Solution?!?!?|||It looks like power button is stuck and unresponsive. You may have to send monitor to a service technician.
