My GH1 has stopped working. Every time I turn it on I get an error message “please check that the lens is attached correctly”. I have taken the kit lens off and reattached it several times and I have carefully wiped the lens contacts clean and it still won’t work. I called Panasonic and they suggested I take the battery out and wait five minutes and then try again. It’s still broken. Does anyone have any experience with their GH1 malfunctioning in the above way?
