I have just received a DSC-HX20V which appears to have an issue with the power switch. If I push the on/off button the green light on the button illuminates but nothing else happens and the light remains on. If I then remove and replace the battery and push the on/off button the green light on the button illuminates and the lens extends as one would expect. If the camera is then switched off it can be switched back on again without any problem as long as this happens within approximately 5 minutes. If it is left for longer than 5 minutes the green light on the on/off button illuminates and again nothing else happens other than the green light reamins on.
Any help would be appreciated.
