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.

It is cases like these posting a shot of the issue from your smartphone can be very helpful to the forum. A picture truly can be worth a thousand words in diagnosing problems like this one.
