I agree. Check on the small electrolythic caps around the sync generator IC. They should be 1UF/50V to 10UF/50V. Anyway check all the caps around that chip and in the Power Supply area. When they go bad the monitor doesn't start, specially those around the switching IC on the Power Supply area and they are the reason why the PS tick, tick, tick... More specifically there is a cap in the PS next to the SMPS chip (normally from 22UF to 100UF) that filters the feedback voltage rectified from the switching transformer back into the chip to keep it running after it has started. If that cap goes bad, then there is not enough voltage to keep the chip running and therfore it goes off again and so on. That's why you hear the tick, tick, tick. Accordint to what you are saying that seems to be the problem.
Good luck
