I have recently use the RES to keep my 2.5 year old calm during a trip. I have not use it very frequently since it is my wife's car. However, this time when I flip the screen down, it flips all the way around pass where it ususally stops slightly pass the middle. I know that there is usually two positions that the screen can be open to (one being almost vertical and one slightly pass that, both have a click stop). But this time, it went all the way around (like you can seen the screen from the front seat if you look up and back). When that happen, the screen goes blank. It the screen stops broken or it is suppose to do that?
