Beamo showing "Not support" in display

When switching on our new Beamo it happens from time to time that the display goes all blue and is just showing “Not support”. When this happens we used to just switch it off and on and afterwards it will start normally. Today this didn’t work, it kept displaying “Not support” until i unplugges it from the mains and waited some seconds. After pluggin the cable back in it worked. Is this a known problem which can be solved without sending it back to the dealer where we purchased it?
