No video, no audio
Just like the title says, my Xbox 360 has stopped displaying video, and I have no audio. I've tried switching from HDMI to component cables, and also using a friends HDMI cable and TV, to no avail. My TV still displays "NO SIGNAL," while his actually displays an incredibly distorted/warped version of the boot up screen, but, again, no sound.
I've heard that a fix requires a saudering re-flow, but I don't know what of. I've also not tried to "towel trick" quite yet. Any help would be appreciated.
