Rebuilt a Hantarex MTC9000 that was non working. Got a lovely sharp colourful picture now but i cannot get the vertical hold to stabilise. Its like there is no middle ground for it to lock in it either scrolls up or down when you adjust the pot..
Doing my head in, even changed the TDA1670a vertical control chip, no difference
Also checked the vertical hold pot is ok on the little remote board to.
I did add the extra jumper for both syncs already to as that was the only way to solve the horizontal sync problem i had to
Firkin annoying monitors!! ha
Anyone got any ideas please
