Short the two holes with jumper and disconnect LVDS cable. Power set up.

IF alls well, test-patterns displayed. If not you'll have a SUS board or IPM/PSU problem. Suggest you check all the supplies such as Vs, Va, VSC -Vy etc are within tolerance....

(Suspect loss of Va, from PSU or maybe failed SM fuse on lower address boards....)

Cool beans nice fix common issue on these is the 100uf 25v caps on the control board failing. Also you might want to consider recapping the Psu.
