I've owned the PDP 434 for two weeks. I soon noticed that I needed to adjust the height of the image to remove the black band from the top of the screen, even when in zoom mode. Also, when watching films (DVD) with subtitles or programs (via NTL box) with the information bar at the bottom of the screen, I can only see the very top edge of the writing. I have adjusted the vertical height to its maximum, changed all the various aspect ratios, turn off/on Wss etc, all to no avail. Any advice would be much appreciated.
