i mentioned in the above post that line transformer (fbt) is replaced , yoke also replaced then also tv shuts down , when i remove yoke conector , h- section works
 

i had that prob with plano and sansui sets mostly that fault attacks flat screens,i am not sure which coil is exactly affected but i think is the horizontal ,just change the Scan Coils.
