Pretty sure that is NOT the vertical area...I see a SMPS transformer--looks like the power supply.
As for the 200 volt diode and capp--likely it will be near the flyback, and colse to a connector that leads off to the CRT board. It will come right off of a flyback pin--usually through the resistor and then to the diode and cap (perhaps a 4.7/250 ,10/250 or such) and then to the CRT board.
