I have a Mitsubishi 65" Medallion Projection TV, WS-65819. When I hook up my WII or XBox 360 or even a DVD player, I hear sound, I see the picture, but it seems as though it's scrambled. I use ATT Uverse and that works fine, just can't get the picture for my game systems to work. Both game systems use the 3 plug (Red, White, Yellow) connectors. I have tried all inputs in the back of the TV, but still not working. Please help! Thanks, Phil
