Cut the culprit. No lights on that column at all now. No power at j137-2. Bad Q97. Will sort that. Or maybe I'll just hack into another column
Found some other nice work whilst pulling power driver out. In the high power section of display driver there was three resistors soldered in a row in the one position. Like a rainbow coming out of the board but no gold to be found anywhere.
Thanks guys for the help.
