When I take a photo, the image is displayed for a couple of seconds as usual and is stored on the card correctly. The camera is functioning correctly apart from the lack of display when I press the shutter half way down.

Thanks Chris.
Is anything being displayed though on the screen when you take a photo?
Sorry I was not clear on that
Customer: replied 3 years ago.

No, not as the photo is being taken.

Expert:  Richard replied 3 years ago.
ok, but apart from this, like menu items or anything at all?
Or the screen is constantly black?
Customer: replied 3 years ago.

Nothing. The rear display screen is constantly black - until after the photo is taken when it is displayed for a couple of seconds as it is being stored on the card.

Thanks, ***** ***** the issue
The LCD screen is shorting out Chris, this is why it behaves like this. It is soon not going to function at all. The issue will be the controller that powers the screen. If the camera is under warranty, this issue will be covered.
To repair this though is going to exceed the cost of a replacement camera so I would avoid a repair if the warranty has expired. But it is the LCD control (hardware component) that is failing sorry.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
