Wii Freezing Issues

[Ping]

So, whenever I try to start up the two Virtual Console games on my Wii (Super Mario Bros. 3 and LoZ: A Link to the Past), the screen freezes and doesn't change, yet I can hear the sound progressing fine, indicating that the game is working, just not showing up properly on the screen. I have noticed that when I press the Home button on the remote, and then exit out of the menu, the screen does update, but otherwise it doesn't change in game. I honestly do not know if it's a TV issue or a game issue, since I was able to play both games without any problems before. Does anyone have a fix for this, or at least know the root of the problem?

Is there another TV you could test it on? If that doesn't work, try deleting and re-downloading the games (I'm pretty sure the Wii lets you do that, but check before you delete something lol)
