So today I came across an issue with my TV. I was watching tv on my cable input and decided to play some xbox. I turned on my xbox and swtiched over to my xbox input. The xbox was on but the screen stayed black. I then tried to switch inputs but I could not. Then when I powered down the tv and went to turn it back on, it took a sec but did not turn on. Only the blue light came on and it blinked 10 times. When I hit power again, it turns on, but still the screen stays black. My other inputs work, but not that one. Anyone know whats wrong?
