Sanyo Digital Camera Screen Issue?

[Edith S]

I dropped my Sanyo S122 digital camera on gravel while trying to take a picture. I've had it for four months. Immediantly, the monitor had a small black spot on it, internal, not external. Shortly afterwards, three weeks later, the entire screen is covered in a faded black, and occasionally, the top right corner looks like a internal white and lined sheet of paper. How can I fix this or whom could I contact. Thanks!
