Opps i mixed the two signals. It's the Horizontal signal that's the bottom picture. The Horizontal at the chips seems correct though, i'll see if i can get a picture.

I can see you measured the 50Hz v-sync signal, but did you measure the h-sync signal, and if so, what was it?

Solved! It was the resistor that has somehow broken. Nothing that i can see visually though. but when i bodge over the resistor for Horizontal i get a picture :)

:bravo:

What resistor are you referring to exactly ? IIRC there are no resistors on V&H sync ?

This is the resistor om talking about:

since the ohm is so small i'm thinking on just having a wire there instead :?
