When my son plys his wii we have to turn the tv to 1 video all of a sudden today when we press the button my the remote it says s video not 1 video anymore. If you press the button on the remote you can get 2 video like always but not 1 video. You can hear the wii music but no picture just black. I need to find out how to get it back to 1 video and get off this s video. We have had this TV for 4 years never had this happen before! Can anyone please help me.
