Thank you!

I changed bot of these capacitors and the tracking problem is fixed, the picture is stable vertically, colour is stable, and I'm able to sweep the tracking so that i get noise bars at the top or the bottom of the video image. But ... the image 'tearing' problem remains (as in pic 4 previously) Is this a signal processing problem that could suggest further capacitor replacement is required, or a mechanical problem .. worn heads?
