Prevent TV from turning on with Xbox?

Hi Ricardo,

Thank you for your prompt reply.

Yes the console turns on my TV through the receiver (which is therefore on stand-by).

I'm on the latest firmware.

What I'm wondering is whether the CEC signal from the Xbox can turn on both devices at the same time or whether the passthrough option prevents this from happening: similarily, when the Xbox turns off the receiver, it doesn't turn off my TV.

Guess you have set up the xbox to turn on the tv and receiver. So it tries to do that when it is turned on (Xbox cannot sense that it is already on).

Your tv model responds to turn on/off with the same infrared signal. So when it is on, it will turn off and vice versa with the same command. That's not a fault/problem from the xbox but from the tv manufacturer.

So two options:

- always turn on the tv by turning on the xbox and turn the tv off by turning the xbox off

- or do not let the xbox turn on your tv and do that manually

Update: This problem is now occurring EVERY time I turn my xbox off (in instant on mode). The error code that it reports with the TV "taking too long to open" is: (0x8027025a). I have to unplug/plug it back in after every time I turn it off! Is this the
same with the rest of you or were any of you able to find a fix that prevents it from happening? When is someone from Microsoft going to acknowledge this thread?...........

You can turn off auto updates in the Xbox Settings to prevent this from happening again.

Hi Ms. SoftKitty! I understand this problem completely, because it happened to me, and at one point it was also powering off my PC monitor (because it received commands on the same frequency!) The problem is, most TV's do not have a separate "power on" and
"power off" command, they are one and the same. SO, when your Xbox is turned on, your Kinect sends out the power signal, regardless of whether or not it's actually NEEDED (it can't tell your TV is already on.) As you've discovered, the problem with that is,
if the TV is on, the Power Signal has the opposite effect and TURNS OFF your set. A pain, I know.

The only way to prevent this from happening is by pressing Menu, going to Settings -> TV & OneGuide -> Device Control -> Power Settings and disabling the option for your Xbox to power on your TV when it is turned on.

I hope this helps!
