50.0cm (21 inches) measured diagonally with 90° deflection.

Locate the vertical deflection IC pinout. Confirm supply voltages (e.g., +25V and -25V) and identify the feedback loop components. panasonic tc-21rx20c circuit diagram pdf

The diagram will list specific voltages (e.g., 140V, 24V, 5V). Use these to narrow down which component has failed. diagnosing a no-power condition

Usually features a TDA series or proprietary Panasonic "Jungle IC" for signal processing. panasonic tc-21rx20c circuit diagram pdf

: Standard operating range of 27.5kV to 28.5kV at zero beam current. Circuit Boards :

Without the schematic, diagnosing a no-power condition, vertical collapse, or distorted audio becomes guesswork. The typically includes:
