Then with powerboard fully intact, i would try forcing it on, not exactly sure how to do it in this one, I have worked on this one before but it's been like 5 years ago so that memory is mostly gone one of these smart techs probably knows how tho.

see if d4 checks the same as d3 and d10.

They all seem to be fine (they read the same), the only thing that has no continuity at all is T1.

For now you need to get where the backlights are on when powerboard is unhooked from mainboard, so I would leave the cable off til then.

Yes, I tried that at first but still no voltage on the cold side.

Yes, that is the board, which pins should I short to turn it on?
