I own a Sony Model CCD-TR5 Video Camera which quit working. It has been sitting without use for a year. The battery is still good and takes a charge. Hooking it up to the electrical cable direct does not start the unit either. It acts like an electrical circuit separated or something corroded inside. It has not been dropped or abused. Can you help?
