@jfm75 can you please explain how the germanium diode solution works? I guess I just don't know enough about electronics to understand how the PAL signal through a germanium diode supplies >1V to the pin If I had to guess I'd venture it has something to do with rectifying the PAL video signal ...

Hi all,
