The camera vibrates, shakes or makes a mechanical noise when the power is turned on.
The camera is making an initial reset operation for the lens drive motor when the power is turned on. If the initial reset operation is not complete, the camera may vibrate, shake, or make a grinding noise. To resolve this, turn off the camera and remove the battery. Then, put the battery back on the camera and turn the power on.
If the issue is still not resolved, it may require service.  Go to Product Repair.
