Unplug Y-sus and Z-sus, then see if it powers up.

OK, by no power, what do you mean? Does the power LED come on? Do the relays click? Do you have voltages Vs and Va?

On the control board, do you see two points marked EXT AUTO GEN?
How about some pictures of the boards? I don't have this TV in front of me.
