So I sold my old GH1 on ebay. Buyer is reporting that he gets a yellow exclamation point error message when camera powers down. I don't recall seeing that, but I wasn't using camera all that much. A little Googling led me to dvxusers forum where they seem to say that entering the service menu causes that exclamation point message. I'm wondering what any old school GH1 shooters have experienced? Any insight in to the exclamation point message? If the camera I sold has an issue I want to refund my buyer, but it sounds like this may not be an issue at all. Thanks in advance!
