Page 4: Circuit Description
CIRCUIT DESCRIPTION 1. POWER SUPPLY control) The chroma signal is divided into R-Y and B-Y The power supply circuit of the EB4-A chassis is chroma signals, demodulated in IC201, and output from composed of a rectifier smoothing circuit, an oscillation pin30 (R-Y) and pin31 (B-Y). -
Page 5: Horizontal Output
6. HORIZONTAL OUTPUT Pin25: Black A horizontal oscillation signal is output from pin37 of Pin26: IREF IC201 and switches the drive transistor Q431. This Pin27: Odd/Even output switching signal is current amplified by the drive Pin28: GND transformer T431 and drives the output transistor Q432. Pin29: - When Q432 becomes ON, an amplifying current flows Pin30: V-deflection stop output... -
