Can you be more specific ?
The camera showed only a blue screen and no image ? What do you mean by the camera changed setting - which setting ?
It could be a corrupt file. Low format your CF card or test with another card.
It could be a broken LCD part.
It could be a sensor problem.
Until you could tell more details or post a pic of the blue screen, it is difficult to tell (guess) what the possible problem may be.
