                Unplug Y main and X main (samsung uses X rather than Z) from Psu see if Va persists.

                      When you tested the PSU did you unplug all the jacks from the board and did you put a dummy load on VS?. Was this a self-test? ie: did you use resistors to self power the board to the ON state without signal from the Main Bd?
