Picture capturing button broken

I have read the entries here and I think the same thing has happened with my camera. Is the button to snap the picture the "release assembly" part you are mentioning in your posts? If so I have ordered it from the tiger direct site. The sony site didn't bring up the part for me. I am hoping I don't have to send this camera to Sony. I have already ordered the packing slip and put my credit card in but have not sent the camera yet. Is that their standard fee to look at a camera? $181.00. I hope the suggestions here on fixing it yourself are going to work. I am pretty handy so if there is anything you can prepare me for when the part comes? Will post results. Thanks
