  • 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 EB3-A chassis is chroma signals, demodulated in IC101, and output from composed of a rectifier smoothing circuit, an oscillation pin30 (R-Y) and pin31 (B-Y). These chroma signals pass circuit, a control circuit and an output rectifier circuit.

    6.HORIZONTAL OUTPUT Pin34: TEXT/16:9 SELECT OPTION A horizontal oscillation signal is output from pin37 of Pin35: Key scan 1 IC101 and switches the drive transistor Q431. This Pin36: P-ON(TEXT) switching signal is current amplified by the drive Pin37: S-VHS output transformer T431 and drives the output transistor Q432.
