samsung ps50c450 clicking, no pic or sound

[wills123]

got this set in to look at for a mate, when switched on it i have stanby voltage 5v, press power button and it just clicks every few seconds.
Pson drops to 0v and raises with each click, i think mainboard/av is telling it to do this as its detecting a problem.
I think the psu is faulty becuase i dont get all the voltages marked on the pins where it goes to main board/av,
i only have pson and stdby, the other pins marked 15v and 5.3v have no power.
Just after confirmation really that im right in what im thinking
also i have no voltage going to the control board in the middle
thanks
oh the psu is, bn44-00414a

grounded pson and dont get those voltages from the psu still,it stops it clicking but i cant do the test using the jumper on lvds as theres no power to it or the y-main
presumably doing this they would be there,
also tried with everything disconnected to see if voltages come up but nothing.
