It's the "General Hardware Failure" one. I had kind of hoped being a 3/4 ring meant it WASN'T a full ring, but I guess the full ring means a/v cables, although apparently unplugging it may work.
You know what really kills me? I was having an AWESOME first ball in Theatre of Magic when it happened. Things were looking good, then everything turned purple, then black (or maybe that was when I shut it off, I don't remember the details now), then when I turned it back on, red lights. That happened to me earlier in the afternoon too, during a much worse play session of ToM - I hit a bumper and all of the sudden there was a buzz, the screen went all weird like in a cartoon where a villain hijacks a TV signal, then froze.
It's very much the principle of the thing - while I'd love to have an excuse to go buy a smaller, sleeker, kinect ready, bigger hard drive (mine is almost full), and built in wireless adapter (the new ones of that right?), I just feel like the time to do that should be up to me... like, when they're cheaper.
