I recently picked up a used Sony Wega 24-inch CRT television believing that it could handle 480p or "enchanced resolution" video signals. Upon selecting this particular video mode in the Wii options menu I found myself starting at a very flickery display. The image is so flickery, infact, that it's impossible to navigate the menu in order to select the original 480i resolution that works for this television -- Is there a way to somehow restore the Wii back to factory settings without wiping or re-formatting the Wii's internal disk drive so that I can get back to gaming?
