This seems to be a 2008 camera so it could be getting old. At least the battery is well past its prime. Did you put in a new freshly charge battery?
I also see they issued firmware for this model. Is the firmware current?
<span id="INSERTION_MARKER">Hi there folks,<span>
<span>Was just wondering if any you guys have come across this problem, can offer help, or point me in the right direction to seek help.
<span>Basically, over the past couple of weeks my Lumix G1 seems to be messing up. Firstly, it will not switch off. The on/off switch makes no difference whatsoever. To turn the camera off I actually have to manually remove the battery. Also, rapid shooting no longer works. If I hold my finger down, it takes one picture only, no matter what setting I have it on.I would really appreciate any help you can offer on this.
