I just bought my son a new 19 inch widescreen LCD TV Monitor to use with his Wii. We have the Wii on the RCA cable inputs for the monitor of course. All the new Wii games work fine as does all the standard Wii menu items. The problem is with the games we downloaded from the Wii Shop. The only game you can play and see is Super Mario. Donkey Kong, Pinball, The old Zelda only show up as a black screen when you try to play them. You can hear the game going on and when you push the "home key" to get back to the Wii menu you can see the graphic of the game behind the Wii button choices for Close, Reset or Wii Home.
I have tried making all the adjustments on the TV for brightness, contrast etc and nothing helps. Any ideas?
