I am having trouble with my xbox powering on and working correctly, also there are...

Hello Mara, sorry to hear you're having trouble.

Have you tried a factory reset on the console? If not I'd recommend it. Are you able to get into the console settings? If so then reset and Keep your games and apps. Your saves will be safe on the cloud.

Hey. I am also having trouble with my Xbox 360 controller. It isn't connecting when I try to use it. And do you mean to unplug my Xbox 360 E from my power strip when you say, "Killing the power strip"?

I've found just by observation, that if I turn that xbox off with the remote or the console button, the "Xbox On" voice command is not working. If I command it to turn off with my voice it seems to turn back on with my voice. Though this is anecdotal, but
the Turn on seems to work better for me this way. It do have "instant on" configured in the power settings.

Also I'm having trouble with the TV running through the xbox with my cable box. The TV stream will pause and continue playing after a few seconds. I've had it working correctly for a few day prior but the cablebox seems to reset and the trouble returns.
I'm going to replace the pvr, then if that doesn't work not run my TV signal through the Xbox. It's been a nightmare getting this configured from day one.

I am having trouble signing into my xbox 360 also. Went to a chat ambassador and they said that there is a glitch going on with sign in's on the xbox 360 and that they are working on a fix.

Can you explain exactly what your issue is and what you are experiencing trouble with? I'd love to try and help, but there's not much info to go on in your first post.
