Question Vertical Banding after main board replaced.

Hi

Due to HDMI3 (ARC) failure I have had to have the main board replaced in my Sony 65ZD9 - under warranty from John Lewis by Martin Dawes.
HDMI 3 now working again but there a a number of faint vertical lines on the screen mainly visible on light coloured scenes or panning. I had one or two previously but nothing like now - how can a board replacement cause this and is there anything I can do?

It’s probably due to the movement of the screen, I have seen TVs with no DSE and banding moved from one room to another and then DSE/banding appear.
