TLDR: Xbox sends no audio video signal to cables after multiple freezes stemming from BadAvatar.
I have an unmodded Corona that I put BadAvatar on maybe 6 months ago. It worked fine then. I haven't used it at all since. I went to power it up last night and kept freezing when trying to load BadAvatar. Sometimes it would freeze in the avatar selection, sometimes just after the dump NAND screen, and once when successfully loading into the dash and attempting to launch XeXMenu.
The last time it booted, I got past the dump NAND screen and froze on a black screen. Powered off and on and now there is no signal being sent at all to HDMI or AV cables. The Xbox still powers on. Fans spin, disc tray opens and closes.
My RF Board was broken before this happened and doesn't display any light on the power ring, so I cannot see if it is red lighting or blink sequences.
It might also be worth mentioning that I set it to boot into NXE back when I last used it.
I have tried removing the flash drive and the hard drive but still no luck.
Is the Xbox cooked?
