Xbox 360 powers on but does not boot

  • When I try to start my Xbox 360, I get most of the noise and none of the action.

    • The cooling fans spin up
    • The 1/0-logo in the middle of the led ring is lit, all four parts of the ring are dark.
    • The four lights on the controller blink when started with the controller.

    After that just sits there humming, no signal over HDMI and after 300 seconds it turns itself off. The same thing happens whether I start it with the controller, the power button or the eject button.

    The console is an 120GB Elite model from around the time Forza 3 came out. It's under warranty until December.

    The thing is- I already sent it to Microsoft and it came back with a "dear customer, we looked but we couldn't find anything and therefore didn't fix anything" letter. Indeed, when it came back it was working perfectly fine for the next four or five times, then the exact same symptoms were back. (They did apparently reset the firmware, I had to update that).

    It seems clear that I need to send it back again, but it looks like I'll have to include a heck of a cover letter to avoid further embarrassment.

    Things I checked:

    • The wall socket puts out 234 volts. This is nicely within the 220-240 range it's supposed to.
    • The XBox has (for the entire time that I own it) been attached to a power strip with an on/off switch that I turn off at night and when I leave the house. I've had it directly in the wall socket for the past few days to see if that makes a difference (it doesn't).
    • Tried booting without the hard drive, no difference.
    • Tried standing the console up and lying it down, no difference (it stood upright most of its life).
    • Inspected the back of the face plate, as suggested by Microsoft's online troubleshooter. That's undamaged.

    One thing I noticed is this: when I plug the power adapter into the wall socket, its status light is orange. Only when I power the console does it turn green. Microsoft's online troubleshooter is unclear about whether this is correct or whether it's supposed to be green all the time. I don't have access to another unit to swap parts with. Question: what color is the light on your power adapter when it's plugged in and the console is turned off?

    Is there anything else I could try before sending it in again?

    Microsoft's instructions are clear about sending only the console and none of the peripherals. If I included the power adapter, can I expect to get it returned or would I end up with only a console and no power?

    I think the color on your power adapter is fine. I haven't looked at mine in a while (and I'm not at home atm), but I recall mine being orange when just plugged in and the Xbox is off. I'll try to remember to check tonight when I get home.

    I just checked my adapter, the light is amber when the system is powered off and green when on.

    I've noticed that the 360 won't boot up unless the HDMI finishes a handshake with the TV first. Can you try with a different HDMI cable or with an RCA or Component Video and see if that has the same effect?

    I also have a 120GB Elite.

    Update: I've traded up for a 320GB Slim, it is the same situation. It will not boot until the HDMI handshake finishes.

    This happens to me if I forget to turn on my TV before turning on the Xbox. Check the TV/HDMI cable

    HDMI was indeed the key. This also explains why customer service couldn't find anything wrong. Thank you.

    @BarendGarvelink was the TV off or was it just a bad cable?

    My XBox used to be plugged directly into the TV, which does the handshake even on standby. I upgraded to a home theatre receiver that does HDMI switching, but only responds on whatever port is the active input. Booting the XBox with the TV off never was a problem, with the receiver it needs to be on and on the right channel. I usually turn it on before the XBox, but changed my habit for no apparent reason and then failed to connect the dots.

    My TV won't handshake unless it is turned on and set to the HDMI channel that my Xbox 360 uses. So if I have it on HDMI2, my 360 won't boot.
