I was playing Halo 3 today and I was in a custom game. For some reason, the screen started to gain a red tint. I thought the Red Ring was coming but I continued to play because I was able to still see my character and the map. I switched to Gears of War, it got worse and I became worried. I tried GTA IV just to check again and it was still becoming a darker red. The dashboard is fine, its just the games that was getting red. I tried replugging my video and audio output cables and nothing happened. The switch on the AV cable is set to TV as it always has been. I have no idea whats happening. Any ideas?
