Well I just knew
that comment would come back and bite me on the backside!
I examined the pins of the TVP5150 with a really strong lens, concentrating on pin 9, the clock output. Pin 10 (3.3V digital supply) didn't look quite perfect and sure enough, hadn't soldered properly....
I now have a very nice looking stairstep waveform on the video output socket!
Next step will be the mod chips.
Many thanks, Frank
All the best
