Hi folks, Ordered a Chinon CE-4 off eBay. Advertised as working. That was true. Took it out the box and it was working right away. I have another Chinon CE-4 bought from a charity shop. Never had batteries and wanted to try it out. But batteries from most recent chinon (2) into original Chinon (1). Chinon 1 doesn't turn on. But the batteries back in Chinon 2. It was literally working fine minutes ago and won't even turn on now! Any clue as to why this is? I even tried new bsttbatte in both today and neither turn on, am I doing something wrong? Both are in good condition.
