Samsung PS42S5hX - Bottom half of screen flashing black sometimes permanent, does not do this all the time.
Thanks for the solution recently sent, having read a few more problems I have tryed tapping the side of the TV and this removes and brings back the black lower part of the screen, could this mean that it is probably a loose connection/solder joint and would this be on one of the boards that was mentioned, either the Y main board or lower buffer board?

If the picture os goint to lines right from the midpoint downward then most likely you will have to replace the lower y-buffer board part number BN96-02027A. The board is mounted on the left side of the plasma panel when you take the back off. The upper y-buffer board sounds like it is failing as well and this was a very common issue on the older Samsung plasmas. The part number for it is BN96-02026A. Please take a moment and rate my answer. Thanks...
Today, after speaking to the Sansui Manufacturer representative from Japan. He stated that all you need to do is to turn off the closed caption from the TV remote and not the DVR remote. Black screen can occur at the top half or the bottom half of the screen depending on how it was originally setup during installation. Try this and hopefully this fixes the problem.
