Xbox won't turn on using controller

Well, found this too: If you're using an HDMI connection between the Xbox 360 and the TV, it might be that. When using HDMI, the Xbox won't boot up until it knows what the TV is capable of displaying. Although the controller will turn the console on, it
won't sync with the console -- and it's not a controller or console problem, but just a symptom of the fact that the Xbox won't get to the point where controllers will sync until it can properly communicate with the TV. I'd recommend turning off the TV and
the Xbox, disconnecting the HDMI cable and re-connecting it after making sure the contacts are clean. Then turn the Xbox back on first; you'll likely to see the same behavior. Finally, turn the TV back on. With it being switched back into HDMI mode, it just
might "kick-start" the Xbox into a good communication link across HDMI.

Check and make sure the battery contacts in the battery compartment are making good contact, and have you tried connecting the controller directly to the console with a USB cable, that would eliminate the battery issue if that was the problem. If that
does not work then something inside the controller broke. You do have a 90 day warranty on the controller from Xbox support

I would suggest returning the controller to the retail outlet which it was purchased. Most retail outlets have a 30 day return policy.

If this is not an option, your controller has a warranty of 90 days through Microsoft. You may find info on repairing/replacing your controller HERE .

Have you tried changing the batteries? If the issue persists, you will need to have it replaced. To know more on how you can do so please access => Request an Xbox controller replacement | Xbox Support.
