I just recently purchased a used Wii from an Amazon seller. This is my first Wii so please bear with me as I am a total newbie. (I only got it because I wanted something cheap for getting into the Just Dance series. I realize the console is old but I'm not a big gamer so I don't care.) There are some thin flickering pixel-ish lines running vertical, evenly spaced across the screen. It seems they are only on the Wii menu screens, however they also appear on things like MiiChannel and Netflix. They don't seem as apparent on games. I'm using the standard AV cables. Do these lines mean something bad? I need to know so I can contact the seller if this is a problem. I'm rather concerned. Here is a picture of what it looks like. I have tried 2 different tvs and it's the same on both. Any info would be greatly appreciated!
