This sounds like a broken or cracked LCD screen. The backlite is working, thus you will get the white screen. The LCD could also be disconnected internally, or has other problems. But this is a direct problem with the LCD.
A camera like this can usually take pictures, and you may be able to use it to set the menus by using the video cable to the TV or computer screen (some flat screens have video inputs).
I had the same problem with mine. I searched the web and came across this one. My camera had a black screen but everything else worked. I read some of the comments and a few people said to hit it. I hit the camera in the side of my hand a few times and it started to work. Thanks for the info. It sound carzy but it works.
Now working Nikon coolpix
There is no black and white mode in a Nikon Coolpix L100 camera. You can take a picture and then convert it into black an white through any photo editing software like Adobe Photoshop.
