That's a first. I don't know whay that would/could happen either. They are inputs, not outputs. I wonder if he mixed the separate cables up, Green (Y) to Blue for example? First, unplug the set for a few minutes and see if that fixes things, Second, try a service mode reset (assuming there is one). You will have to search for the service mode access procedure. You can try to ask your local Sharp authorized service shop. .
