Who or what is pbt? My bet is on the oscillator circuit containing the 4.43MHz crystal (which is a shame as I haven't got an oscilloscope and wouldn't have a clue how to fix it even it turned out to be that). Is my information wrong or is this circuit a kludge? My info says that the video chip expects either a 8.9 or a 17.7 MHz clock (can't remember which), whereas the crystal is in fact just 4.43MHz. imc
