is just glass, I don't think that is the source of the problem. More likely the imaging chip, or other electronic component not doing its job for whatever reason.
It is likely the diagnosis and repair will be more than the expense of replacing the camcorder - but you won't know for sure unless you contact a Sony authorized repair shop - or Sony.

I have a Sony Handycam HDR-CX110 that has begun to give me a "snowy" screen on my LCD when I open the camera. The screen will appear with the lens cover open and closed, which leads me to believe something is wrong with the lens.
All of the functions on the touch screen appear and function as they normally would. The camera still records, but the video records the same snowy mess that appears when turning the camera on. The audio records perfectly fine.
Here is a video of what I see when opening the LCD door.
