Hi,  I have a Sony DSC-T99 compact camera.  When powering on it produces a 'buzzing/vibrating' noise

causing the screen image to 'shake'.  Not aware of any physical damage, ie: having been dropped etc.

Sometimes when powering on the camera will work fine.  Pick it up on another occasion and the above

fault occurs.  Could this possibly be a battery fault ?  I do not have a spare to try, and am reluctant to buy one

as the fault may well be a serious issue with the camera itself.  

Any advice would be appreciated.

Regards,
