My LS locked up on me today. The screen froze, then I went for a reset. I held the power button down for 10 seconds until it shut down, then restarted. It powered up, but the screen is inactive. I tried powering up a few times. Each time I turn it on, the light below the "action" button blinks red, yellow, then green over and over again. At the same time the light below the "check" button and above the "home" button remains a constant green light. Is there a trouble shooting code that would be indicated by these light patterns? Any advice about what that could be would be awesome. Thanks!!
