Hi,

My Sony digital camera has a violent vibration when turned on in camera mode. This is a shirt pocket sized camera. It feels like a motor running inside and the screen shows movement (like you were shaking it rapidly).

The problem is not consistant. Sometimes I turn it on and it operates flawlessly. Last week, when it was cold (high 60's, low 70's) the vibration occured. 

Thanks for your input.
