I have a Sony Mini Hi-Fi Component System, Model MGC-RV8. As it was playing, it came to a halt and there came the message "Push Power Protect". We followed the instructions in the Operational Manual for Trouble Shooting. We removed the speakers and tested the ICs and other componets. They seem ok but when you connect the head, it still says "Push Power Protect" and can not play. What could be the problem and how can a technician sort out the problem. Please help.
