Kodak DX7590 black spot in pics

[metro7100]

Hello I am new to this and was wanting to know if anyone could help me. I have a Kodak DX7590 and when I take pictures I have a black spot in the pictures. The spot is on the LCD screen and also when I print pictures, can you tell me what I have done and what I can do to fix this problem?
Thank you for all the help you can give

You'll really have to post a couple of pics for us to have a look at to give you some ideas. Is the "black spot" always in exactly the same place? Is it a regular shape (perfectly round or square etc) or irregular? Does it have sharpish edges or is it very fuzzy around the edges? Is it there at all focal lengths? It's difficult to make a guess without seeing the images.

Cheers :)
