Yes thats what I noticed with mine as well. When the light blinks regularly, it works good. When the light quits blinking or starts blinking erratic is when it is acting up. I used an arduino board so its not just limited to the iduino. It turned out that when it was acting up, it was not getting sufficient voltage. Even a reading of 4.8 volts was too low. On mine it was the display transistor acting up and sapping power. Id try unplugging different things from the board and figure out just what is making it act up.
