XBOX 360 + HDMI -- Turns off w/TV (SOLVED)

Orogogus

I have a 360 connected to a TV via HDMI, and the 360 automatically shuts off if the TV is off, or if it's not set to the HDMI input. It also doesn't turn on until the TV input is switched over to HDMI. Is there any way to disable this behavior, and have it just start up and stay on regardless of the TV's status?

There's probably an option on your television you could adjust, I'd start digging through the manuals.

I think it's part of HDMI... My 360 is plugged into my monitor and it won't turn on until I switch to HDMI mode as well.

I connect my 360 to my TV via HDMI and have never come across this. I will often hit the on-button for the 360 prior to even touching the television. I've had no issues anywhere close to this.

Well, the 360 turns on insofar as the power lights up, but no matter how long I wait once I switch to HDMI it goes to the logo first. Also, it tends to take several seconds, with the TV first showing no input, then audio only, and finally the bootup.

I'll check the manual, but I did look through the TV menus without seeing anything promising. I was wondering if it was the 360 or the TV, though -- guess it's the latter.

I have the same issue. Seems to me it's the 360 causing this. If I boot the 360 before opening the tv, no HDMI input is detected, so by default the console boots with RCA settings. When I then open the TV the console detects the HDMI input and automatically reboots to return to your chosen connection type (HDMI).

I'm not sure about your guys' TVs, but mine has an option that you can have it turn on other compatible devices via HDMI. Check your manual.

Yes.

Certain televisions and receivers have "power control" over hdmi connected devices, I used to experience the exact same thing on my old receiver until I upgraded to a new one, and stopped using the component connector to get optical audio out.

here's a quote of a quote I found on google, seems to be exactly what your issue is:

Here's a quote:
"I have the same problem. It's actually the Xbox... Question are you using AV cables to get Optical audio? I'm using the Component AV adapter sliced up for just the Optical output and HDMI. It restarts when I switch components.

From what my understanding is, the Xbox automatically detects when you switch to and from HDMI . And if you have the AV cables hooked up also it switches to the next connected mode which is: Component. The problem is the Xbox requires a restart when it switches modes.

If i take off the Component AV adapter, and just have HDMI the Xbox will not restart."

I did just what this guy describes: I'm using the XBox's component out for the audio but I'm using the HDMI cable for the video.

Problem solved.

So it looks like your option are either:

a. use only component
b. find a receiver/television capable of decoding audio over hdmi.
c. if you're already using only hdmi, simply unplug the a/v cable on the back of the 360

That worked. I yanked the optical connection from the 360 to the receiver (which is only plugged into a pair of speakers anyway), and just let the TV go to the receiver instead, and everything's hunky-dory. Thanks!

I have experienced the same problem in the past. You should not need to turn off the CEC function on your TV. First, go to your XBox settings** then go to SYSTEM, then CONSOLE SETTINGS, then DISPLAY and finally DISPLAY RECOVERY. Now make sure that this set to ON. This should cure your problem.
