Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
JustAnswer.com itself does not do repairs; we do advise upon possibilities for self-repair and other repair services and their availability.
In this case, self-repair is probably out of the question. I would recommend sending it off to Casio's repair service. Casio has one Factory Service Center, in California... see this page:
If this answers your question, please rate my work, so that this case may be closed. Thanks, ***** ***** luck.
