SMPS SCHEMATIC
Fixed
voltage (or Auto voltage selectable) power supply circuit is used in this unit. If Main Fuse (F1601) is blown , check to see
that all components in the power supply circuit are not defective before you
connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to
fail. The voltage for parts in hot circuit is measured using hot GND as a
common terminal.
DIGITAL MAIN BOARD SCHEMATIC
The
order of pins shown in this diagram is different from that of actual IC3104. IC3104 is divided into eight and shown as
IC3104 (1/8) ~ IC3104 (8/8) in this Digital Main Schematic Diagram Section.
