I have put in the wrong tv resolution setting and now The tv screen is blank as the wii is sending a 60hz signal instead of a 50hz one. How can I reset the wii without a screen to read.
Go to a friends place, or a best buy or other electronics store and hook it up there and switch the settings back.
I made this mistake myself, but I got out of it by getting back to the wii main menu and changing the settings based on my memory of placement of buttons and pages.
