13-1 Overall Block Description

Horizontal & HRS Circuit
※ Bias Circuit structure of S64A sis the same as the existing S62A Circuit.
■ Circuit Constitution.
1. Horizontal Bias Part
- Controls the high voltage generation and horizontal bias.. FBT, HDT, CT condenser etc.
2. Vertical Bias & Vertical (North / South) Correction Circuit
- While mostly controlling the vertical bias, also corrects the picture lowering of top and bottom. ..LA7845, Vertical TRANS, etc.
3. HRS (Horizontal Raster Shift) Correction Circuit
- A correction circuit of Linearity distortion on the left and right side of a picture which is caused by awry electron beam from an
electron gun.. Correction S/W and surrounding circuits.
4. D/F (Dynamic Focus) Correction Circuit.
- Improved Focus feature circuit due to the widened angle of a picture¡¦..D/F Trans, Vertical/Horizontal circuit
5. E/W (East / West) Correction Circuit.
- A circuit for correcting the spool shape which appears on the left and right part of a picture. This is caused by the difference
between the distances from the center of a picture to each corner. KA393, FQP630 etc. (Adopt PWM circuit)
