my xbox turns on for a second and immediately turns off

It is not the power supply..i had the same issue..when I would plug the power supply into the console the orange light would instantly turn white for 1 second, then back to orange, then white, orange, white, and after the 3rd white it would just stay orange
for eternal life until you unplug the ***..i did all the trouble shooting for almost 2 weeks before calling Microsoft and they first told me it was a faulty power supply and gave me some *** analogy about how the little fan gets fried due to "me" improperly
placing my power supply in a ventilated area (which It obviously is).. so while I was waiting on the order I found a replacement power supply brand new at a local Disc Replay for $60..so I figured I'd bite the bullet since either way I'd have a backup when
my other one comes back, but turns out the same *** as my (fried cooling fan) power brick paperweight..i was furious simply because I trusted Microsofts customer service technical representative telling me what the problem was..but honestly It was kind of
worth it to try because I found out that there's actually a problem with my console (according to REP#2)

So now it's been a week since I shipped out my console and 2 weeks for my perfectly functioning nothing wrong at all power supply..so in another 1-2 weeks I hope to finally have a 100% working game console that I've spent more time troubleshooting than actually
playing ..fingers crossed

I just had this problem... Power brick solid orange LED, won't turn on by controller, manually turns off but shuts down in 1 second. I tried everything on the support page to do it myself, still didn't work. I called support and they just tried to get me
to do everything i just tried on the support page. I literally tried everything about ten times and still nothing worked. I was about to buy a new power brick but i figured i should try everything again.

The ONE thing that finally worked was hard resetting the xbox. Within the second from turning it on, I held the power again to reset it and it worked. I tried this ten times before and it didn't work until that last time. I suggest anyone who has this problem
to try over and over to reset it this way until they get it to work. The timing has to be so precise for you only have such a small window of opportunity to get it to work, I'm saying it is
VERY PRECISE on timing. Just keep trying until you get it, this was the only way I was able to get mine to work.

Also if this works and the same issue comes up a couple days later, make sure to change your power and startup settings to energy-saving mode.

Hey there TheRipperDannyB!

Because this thread is quite old, please create a new thread detailing your issue so we can help you out. Thanks a bunch, cheers!

I am having the same issue, and have tried this repair message (and a few others) at that, anyone got any solutions?

Thanks for the tip. However, as this thread is fairly old odds are the OP has solved their problem.
