tricky pb witn samsung plasma tv ps-42c96hd

[Ere]

Hi,
this just cannot give the vs-on signal to the power board so that it can power on, have changed the power board, nothing wrong with z-sus and y-sus, the white light in front of tv count till 5 blinks then all the output on psu comes on and remains all time, except the vs= 190 is missing, and no vs-on signal measured, this signal comes from the board wich is under the main av board, it's could be a bad t-con board since it controls the vs-on signal
if anyone have the dump for this board please
