The dip switches make no difference (different screen but game won't start).

Pressing the chips with the ball solder contacts makes no difference.

The video ram doesn't get hot.

The ram has 100 tiny legs per module, 400 in total. And then there is all the re-balling. Therefore the board is scrap, as far as my abilities go. I will let the owner know.

Retroman - if you fixed a board, would you consider selling it back?!

The cabinet (inc monitor) will be adapted to a mame light gun machine, if a replacement working board doesn't turn up before then.

Thanks for everyone's help!
