I bougth and old Sears Video Camera/Recorder for $10.00 and for my electronics practice repair. My actual problem is when i push the power switch i get to run the recorder for only one minute but after that the power switch light got off. In this shortly minute i can start play and i can see the picture in the view aye if i put a video camera in record mode. What is the troubleshooting i have and how can i resolve. Thanks
