Yesterday it was working. Today when I attach the apple composite cable and switch the iPad video output to PAL I can see on the tv a picture but black and white and it is rolling over. The sound comes through fine. In the old days tvs used to have adjustments to correct for the horizontal hold, but they don't any more, but that wouldn't fix the problem as it was working fine yesterday. My wife did watch something on tv since then, but she doesn't think she could have changed any adjustments. If it matters, the tv is a Tosheba CF27G50
