Pentax s5n No Display Problem

Hi, I have owned my Pentax S5n for about a week now and I have come accross a problem. The steps to cause it occur as follows: 1 Turn on Camera. 2. Go to Movie Mode 3. Switch off Camera. 4. When I turn the camera on, there is no display information. The camera has the lcd running with the image from the lens but there is no information on the lcd screen and the buttons do not work (so you cannot change it out of movie mode). Pulling out the batteries and/or the memory card make no difference. To answer my own question. I found a way around the problem by total chance. I turned the camera on while holding the menu button after playing with it for about 30 minutes trying everything I could think of. The lcd starts with a black screen with the 'ver 1.00' and then starts correctly showing the movie mode. If anyone else is stressing, I have no idea what I am doing so try so at your own risk! Can anyone tell me if: a) They are having the same problem b) What I am actually doing to get the camera working c) If this is not just me, If Pentax is aware of this problem and if there is likely to be a fix at some time.
