ok about a month ago i went to turn on my console and it worked except there was no picture, there was sound but no picture. so i went and tried it on different tv's and the same thing happened. so i took the console over to my friends (who has a xbox 360) and unpluged his and hooked up mine using his cords and it worked perfectly. so i just went out and bought a new cord. that worked good for about 2 weeks when the same thing happened again. should i just go and buy a new cord again or do u think its the console thats doing this
Check the cable itself and make sure that you haven't accidentally flicked the AV cable switch over to HD. If you don't have a HD TV it will only play the sound and give you no picture.
