Ok thanks :cheers:
I just tried another HR7191, the same issue, so ruled out the flyback.
Thinking the next step is to change the last electrolytic caps...it might be a bad cap, and its an easy fix if it is, and it may need a cap kit anyway

Tried to adjust the pots, I am unable to get the picture better.
I noticed that the H.AMP and KEYSTONE does nothing at all...

look at all the diodes in the horizontal circuit
