The Panasonic TC-21RX20C is a 21-inch color CRT television released as part of a series built on the Panasonic platform. The GP41Z is a widely used chassis that powers several similar models, including the TC-21RX20CS , TX-21RX20C , and TC-21RX30X .
If you are performing a repair, keep these standard specs for this chassis in mind: Power Source : AC AUTO 110-240V, 50/60 Hz. High Voltage : ~27.5kV at zero beam current. Picture Tube : 21-inch diagonal (A51LYZ295X). Key Components
Ensure the chip is receiving its dual or single supply rails (usually +14V and -14V , or a single +24V rail coming directly from a secondary pin of the Flyback Transformer). panasonic tc-21rx20c circuit diagram pdf

CRT TVs are modular. Look for clearly demarcated sections on the diagram:
Responsible for taking standard AC mains voltage and stepping it down into regulated DC voltages (e.g., 115V for the horizontal output and 5V/12V for system control).
Check the main glass fuse near the AC input. If it is blown, do not simply replace it; check for a shorted bridge rectifier or a shorted STR regulator IC.
Because CRT televisions carry dangerous, high-voltage residual charges even when unplugged, downloading the official technical documentation is vital for safety margins and exact component replacement.
