Samsung Monitor 45bn monitor is dead. But when yoke is disconnected or HOT is removed it powers on. When the yoke is connected the monitor switches off and on with tick sound. Finally Q504 IRF630B gets short.The Horizontal output transistor is okay. I have also tried swapping the Yoke. This problem also persists in Samsung 753S Monitor. What should be done? Kindly help.

Check the yoke coils and the tube itself.
