Facing TV Problems? Ask a TV Technician.
Hi, thank you for contacting JustAnswer.com. My name is Russell. I think that you deserve some sort of answer to your question, even if you already have found the answer yourself.
I think that, if you unhook the Wii from the TV, you may be able to get the Input(1) option back again as an option. Esp. if you turn the TV Off too, for 3 minutes or more, then On again without the Wii.
Thank you for asking your question here at JustAnswer.com.
