Can you post a pic of the camera? I have sold many of these online and I never had any compliants like that. I am also wondering if the reason for lack of responses is that no one on this forum had ever bought a camera like this one. Usually with cameras if something is worng it is on the board itself. Might want to buy a replacement board and try that.
I posted a pic of the camera I think you have, let me know if that is the same one.
