Hi, I have a sylvania tv C6419TD. I do not have a remote, and I'm trying to play some xbox games on it. The xbox is connected, but I do not know how to get to the game mode. I pressed the menu button on the tv, then on "image" I pressed the "up volume" button. It takes me to something that says (-) MODO DE JEU(+) , Then right below this I get HF and EF. I'm not sure what they mean, but I'm just not sure how to get to the game mode from there. Can you please help me?
