Help This Idiot...;)

[Hazeleyes]

I'm new to digital cameras and just bought a Sony MVC-CD500. I feel like such an idiot for having to ask what is probably a stupid question, but ....is the photocell window above the LCD screen suppose to light up? Have I turned something on I shouldn't have? How do I turn it off? I can't find anything of help in the manual. Can anyone please help? Thank you.

Sony cams do that, video and still. Not all still cameras, but most video cameras.
