OK
I swaped over the display for a new one,
Must have done something to it, it is DOA (probably looked at it the wrong way)

So went for the simple solution I should have tried first, I swapped over the whole panel (speakers and DMD) from the spidy sitting next to IM
(This included the cable from the CPU as it was more fimly glued to the display end)
Same issue on this board

So I am guessing something unfixable on the CPU board?
(as most chips are of the too small to be soldered by hand)
