Interesting post. I am just north of you in CR and am working on a Checkpoint right now. It has a PinLED display in it and has been doing some similar things as yours. At various times the screen goes blank, but then comes back. I do not get the command overun message though. I preformed a factory reset after checking the obvious things and it has worked fine since. A little early though to say problem solved. Keep us posted how you come out on this. John
