I’m sorry to hear that you're having this problem with your camcorder.
Unfortunately, this seems to be a service related issue.
Since it's very difficult to diagnose and troubleshoot based on the information posted, I recommend that you contact Samsung's customer service center and try speaking to one of our chat agents at the following link:http://www.samsung.com/us/support/
Or you can also call them directly at 1-800-SAMSUNG.
We appreciate your support of Samsung products, and we look forward to assisting you.
