DESCRIPTION OF BLOCK DIAGRAM 1. Line Filter & Associated Circuit. 6. Horizontal and Vertical Oscillation. This is used for suppressing noise of power input line This circuit generates the horizontal pulse and the vertical flowing into the monitor and/or some noise generated in pulse by taking the H and V sync signal. - Page 9 15. Image Rotation (Tilt) Circuit. 17. Video Output Amp Circuit. This circuit corrects the tilt of the screen by supplying the This circuit amplifies the video signal which comes from image rotation signal to the tilt coil which is attached near the video pre-amp circuit and amplified it to applied the the deflection yoke of the CRT.
