The exact same thing is happening to me.
My TV Model is NS-42P650A11
When viewing the TV in the room with all the lights out the picture goes dark then light in a cyclical basis.
I am viewing the TV in Standard Mode
One CableDVR is connected via Component video cables in Component 1 Input
If I turn the lights on the probem seems to go away. Is there some type of ambient light sensor that could be malfunctioning here that would auto adjust brightness?

The issue is in fact being caused by the light sensor. The reason that it is doing this is due to the fact that you are in a very low light environment and the TV is emitting enough light to cause the sensor to make adjustments. As a result, if you are using the TV in darkness, I would suggest turning off the "Brightness Sensor" which is located in the "Setup" section of the menu.
