Thank you very much for that, Glyn. The TDA 3560 is socketed, so I've checked the pins and socket and they look fine, but I've given them a quick clean, without any effect.

I've re-checked over the boards for dry joints and re-examined the ones I soldered and all looks okay. There is a 13v test point near the Luma / Chroma and RGB boards, which measures a bit low at 12.3v - I'm not sure whether that could be an issue.

The brightness / contrast controls have no effect on the screen.

Thanks again! Neil.
