Hello Rick, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help.
Unfortunately the shutter button has worn out and will need to be replaced by camera tech to fix the problem but it would cost you good money like $100 or so.
I hope these info will help to make decision about this camera repair or invest that amount on new camera. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
