Schematic for the LG 21SB3RV-TP television built on the CW91C chassis, supplied as a 13.1 MB PDF. The chassis code is the key identifier, since LG reuses one chassis across several screen models and cabinets. A technician uses a schematic like this to follow the power supply, deflection and signal paths, find component values and check suspect parts when a set will not start. Compare the chassis label on the rear cover or main board with CW91C before trusting voltages or part numbers from these pages.
