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 6. HORIZONTAL OUTPUT Pin33: Green output for OSD A horizontal oscillation signal is output from pin37 of Pin34: Red output for OSD IC201 and switches the drive transistor Q431. This Pin35: Blanking output for OSD switching signal is current amplified by the drive Pin36: H-sync.
