I am sorry to hear that, because from my experience, that may be a 'breakage' of the camera. However you may try these measures:
- try a different memory card! if your memory card has a problem with storing and writing data, or reading it back afterward, that should cure it (and is much easier and cheaper than a camera repair service if the camera were defective!)
- try a factory reset, perhaps? it would wipe out your Custom Settings and White Balance settings, but not your pictures nor your videos stored on the memory card.
- Also: Try removing the batteries, and leaving the camera on a (dry, non-humid, non-dusty) shelf for overnight, or several hours at least. Then put the batteries back in and try the camera again.
Please let me know how that goes, when you have tried it! And I will help and advise you further. Thank you.
