No HDTV Hi, My Xbox 360 isn't working when I put the AV cable in HDTV mode. I have the cable pluged into a HDTV and I have tried multiple cables and the cables all work on a second Xbox 360 I have. Does anyone know what the problem could be? The 360 works when I set the AV cable to TV mode and plug it in to regular AV. Thanks in advance.

Had this issue? and also a 4 year old gamer.... did this method and boooom back on...thanks

Hi there. There might be some solution out there that would work for you, KboxMod. Here it is : To reset the display settings of the Xbox 360 console to the default settings, remove any discs from the disc tray. Turn the console off and turn it back on. As the console starts, press and hold the Y button, and then pull the right trigger at the same time. The Xbox Dashboard resets the display settings to the default settings, and then automatically restarts the console. Note: If you are using an Xbox 360 Wireless Controller, turn the console on by using the Xbox Guide button on the controller. Make sure that you use the player 1 controller when you do this. The player 1 controller will have the upper-left quadrant light illuminated. Try it a few times, some say it took a few retries to get it working. It might just need a reset of those video settings. Hope that helps, cheebster.
