I was updating a game yesterday when my Xbox screen froze. I tried powering it down, but it would chime and stay on. I then unplugged it from the wall to soft reset it, but now every time I plug it in, it has no HDMI connection, even when turned on, and will do the same thing with the chime where it makes the noise but won't turn off. I've tried holding the sync and eject button when turning it on, but even that doesn't work to factory reset. Microsoft was no help and told me I should visit BestBuy to repair it. Does anyone know of a fix for this, so I don't have to get a new Xbox? I can't find anything online.
