You probably have a flat internal battery due to it being left for so long without a charge in the main battery. The best thing is to charge the camera for at least 24 hours using the AC cord. Hopefully the camera will then perform as expected; if not get back to us.
Hello Mick, after charging the battery direct to the AC cord, I still don´t see an image, I am attaching a photo of the viewer, hopefully you can tell me what do .Sorry for the poor picture, but I think its good enough to see.
Now that it is plugged in, when you take an image even if it does not show up on the screen, is it visible on the memory card when you insert it into an external card reader on a PC or other viewing device? If not, that may indicate a physical fault within the camera.
