Why isn't the screen producing a picture?
The screen has info on it but no picture
Kodak PixPro AZ251 is a 16 Megapixel digital camera from Kodak released in 2013. It has a optical zoom of 25x and Optical Image Stabilization (OIS).
The camera may have a faulty CCD sensor or perhaps there is a problem with the motherboard or both.
Has the camera been dropped at all or gotten wet?
Try taking a picture, (I realize that you cannot “see” what you are taking) and then download it to a computer to check if there is a valid picture or just a black image.
If there is a valid picture then as you say that the LCD screen still displays “info” there may be a motherboard fault which prevents the image collected by the CCD sensor from being shown on the display.
If there is only a black image being shown then it is either a faulty sensor or a motherboard problem.
As you haven’t mentioned any other problems, more likely it is a sensor problem as the camera apparently seems to mostly function OK, i.e turns on/off OK, menus displayed OK etc.
Here’s a link to the ifixit Kodak PixPro AZ251 Repair guide which may help if you decide to open the camera and inspect the CCD sensor etc.
Unfortunately I couldn’t find any replacement sensors online. You may have better luck.
