I have just bought a 3 year old KV-36FS76 and the picture quality is very good. I have downloaded the service manual and adjusted the geomatry as well as I can but one problem persists. The whole picture bows horizontally so that the edges are lower than the middle. This doesn't show up much in normal viewing but does on Sky menus and on 2.35:1 films. From the manual it seems it can only be improved by adjusting Y-splitting correction magnets inside the set. I am not willing to risk this so is there anything else I can do?
