My dell flat panel monitor wont come on

Question

I have had my Dell E197FP for two years without a hitch. Today I turned on my computer and it came on as always. Suddenly, it turned off and came back on. It did it a second time and now I cannot get it to turn on. The light switch is off and would not turn on. I checked the connection at the back of the computer and it's ok. Also checked the outlet and it is also ok.
