My beautiful 70’s black and white TV came from a junk shop on the Holloway road. One day the picture buzzes and fidgets before settling down permanently into a new orientation. The image is still clear and sharp but instead of horizontal, the picture now runs diagonally across the screen at 30 degrees. Nothing I do can persuade the TV to realign itself but I find that a hard-back book placed beneath one side of the set is just the right height to restore equilibrium. The cream TV set now rests at 30 degrees but the image is itself is flat and stable.
