Check the vertical output stage and screen grid voltage (G₂) on the CRT socket.

However, I cannot directly provide a PDF file. Instead, I can give you the most effective methods to find it.

Includes the Horizontal Output Transistor (HOT) and the Flyback Transformer (FBT) connections. Ensure the downloaded file is a genuine PDF

— Useful for quick reference on part sizes and basic block diagrams. 🔍 Pro Troubleshooting Tips Vertical Failure (Horizontal Line):

The Panasonic TC-21RX20C is a classic cathode-ray tube (CRT) television built on the renowned . Despite the dominance of modern flat screens, this model remains popular among retro gaming enthusiasts and vintage electronics collectors due to its robust build and excellent picture quality.

Turn on the TV. If the bulb lights up and the voltage reads a stable +140V, the power supply is healthy; the fault lies in the horizontal deflection or the flyback transformer.

B+ rail to power the horizontal deflection circuit and secondary rails for low-voltage signal processing. 2. Horizontal Deflection & Flyback Transformer (FBT) Instead, I can give you the most effective

If you are not fully familiar with the safety precautions for this equipment, it is highly recommended that you seek the services of a qualified technician.

Before touching any internal components (especially around the anode cap), you must safely discharge the CRT using a well-insulated ground wire and a screwdriver.

The acts as the brain of the television. It processes the RF tuner signals, AV inputs, on-screen display (OSD) data, and RGB color signals. It also outputs the drive pulses for both horizontal and vertical deflection. D. CRT Socket Board (Matrix Board)
