LG service schematic for the 21FG3RG-T9 CRT television, based on the CP-079A chassis, provided as a 1.58 MB PDF. The diagram covers the circuitry a technician needs for fault-finding on a set of this generation, such as the power supply, horizontal and vertical deflection and video processing. Use it to trace rails, check the flyback and line output stages and identify part references. Confirm the chassis code on the main board matches CP-079A before relying on component values.
