Been using my aTV2 for about 2 years now and using it almost exclusively with Plex. But just did a big mistake by changing the HDMI setting from Auto to Yc... The screen changed right away to black. Did a reset by pressing Select-Menu 7 seconds. It came back ok. Wanted to put it back to Auto (was then at RGB), pressed Select thinking it would roll the different options, screen black again. Another reset. Apple logo shows, but right after screen is black. Tried disconnecting power for 5+ seconds. Apple logo then black screen. It's JB with Plex, therefore restore is not an option. Help!
