One of the 6 I've had had that same problem - stuck ring. Don't worry, eventually you'll get a good one. Make sure the whole screen can get completely focused at the same time, I have my computer hooked up to it and it's easy to see if parts of the screen are focused and others aren't. That is another common problem with the 8350.
