Hi

Thanks everyone for your input. Not made much progress. I am now feeding the monitor from the original Commodore Amiga via RGB. The colours have now stabilized, But the black lines are still on the screen, they seem to vary in width and frequency

I have checked the voltages around the fly back transformer, all seem to match with the values in the service manual.

I have also replaced the electrolytic caps around the horizontal and vertical circuits.

I have attached a screenshot of the schematic showing the caps I have replaced circled in red.

It will be Monday before I get another chance to work on the monitor.

Thanks again

Dom
