I have a nv-ds11 which i bought back in 2000, it has always worked fine but have not really used it much over the last few years. When I tried to use it recently a message briefy appeared on the lcd screen about a battery issue and then powered itself off. I have tried to turn it on using the battery and also with the DC in supply but the camcorder still won't switch on. I think I remember reading about an internal battery issue but cannot find the link again. Would be grateful for any advice.
