Touchscreen stuck in timed loop

I've seen another thread on here about the issue I'm having, but haven't seen a solution yet. My touchscreen will sometimes lock up and show the disarming screen with a timer and with the message "Armed Not Armed". The timer will count down but nothing happens. It just hangs there and will not let me do anything. If I put in my code it just starts the timer over again. The only thing I found that corrects it, is to go on the Home app on my TV and arm the system. It will reset the touchscreen and arm it, and then I can disarm again. Has anyone else seen this and found a fix?
