I saw a post somewhere suggesting that if something slipps between the bezel and the screen the rest of the screen becomes unresponsive.
That was me, I had a small seed from a lunch get stuck in there and "press" on the screen's edge, causing it to ignore my touch elsewhere on the display.
I don't think I've ever seen the radio start up with the screen locked - I'm not sure it can. I'd check to make sure the bezel is clean first, then try to resend the configuration data (send to HomePatrol from Sentinel, with the force write boxes checked). If that failed, there's the Reset button in the battery compartment. If THAT fails... it might be time for a trip to Fort Worth.
