In camera mode shows black screen can't take picture, but I go to view pics and i can see them.

First press the DISP or DISPLAY button to see if that corrects the problem. If not, a stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open).
To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

It seems Canon A95 camera got ccd imager chip problem that is why you do not get live view in camera mode to take fresh pictures but camera shows old pictures in playback mode.
Let me know if this diagnosis is correct to proceed further.

Set the shooting mode to a Creative Zone mode. Press MENU to enter the menu. Under the Setup tab, select [Live View function settings] then press SET. Select [Live View shoot] and press SET. Select [Enable] and press SET. Press MENU to exit the menu. Press SET. The image should now appear on the LCD instead of through the viewfinder.

Refer to "Live View Shooting," Chapter 5 in the manual for more details and the limitations of the LiveView mode.

You need to go into the setup menu and turn on the display. This is sometimes turned off when you use the optical viewer or in low power modes. Your user manual will show you how to do this step by step.

LENS SHUTTER OR F PCB PROBLEM

You hit the EVF/LCD button near the "eye hole". When this is pressed it will cycle viewing through either the optical viewfinder or the LCD screen. This display is controlled independantly on each of the modes: shooting, or viewing. This is so you can set the camera to view pics before taking them from the optical viewfinder and view pics once taken from the LCD or vice-versa.

thisis a test

Did you accidentally hit the "DISP" button on the back of your camera? It manually turns the LCD screen on and off to save batteries.

maybe the lemonade was sticky and the shutter can't open? otherwise the circuitry could have been fried if you turned it on before it dried inside.
