This is basically the same as a post over in a different forum, but to summarize, Xbox support had me download a software update to run from a flash drive, which I did, but the update (though successful) didn't work to fix the issue. I let them know, and they emailed back that I'd have to open a repair ticket.
Been running a 360 (and original XBOX) for years without any issues.
Hooked up a One the other night - just updated, set up accounts, no issues.
My son turned it on the next day and got some serious green haze...Now, I know this is somehow related to HDMI; the "fix" (band-aid) is to shut down the TV and the XBOX One, turn off the power strip (yes, the power strip) and then power everything back up.
Next time it's started up, it's ok. Next time after that... back to green again.
Any thoughts? I hope I don't have to ship this thing back!
