No Signal Issue

I think you need to repair your console..if is under warranty open a ticket on support.xbox.com

yea its not a sync problem , tried with several different controllers and tried syncing them all but had no joy...just console switchs on, no signal and controllers refuse to sync. no clue what to try next to be honest

Hi Mamanallah,

Thanks for coming to the forums with your issue with a blank screen. We recommend trying out the
troubleshoot wizard for blank screen. Please be sure to try all of these
and let us know. If still having issue not seeing anything you may want to think on getting the console repaired. You can set one up on the
device support page.

Thanks,

Brad

im having the same problem mine is stuck on a green screen with a controller picture

Have you tried syncing that controller to xbox, it is the button right above where you plug your wired controllers into. When you hit the sync button on the console you have to hit the sync button on the controller it is between the right and left bumpers.
