Check for a collector-to-emitter short on the Horizontal Output Transistor.

The power supply block converts the incoming AC mains voltage into stabilized DC rails. It utilizes a switching regulator to supply the B+ voltage (typically around +140V for CRT deflection) alongside secondary rails like +12V, +8V, and +5V for the logic microcontrollers.

The best approach is to search for the service manual using "Panasonic TC-21RX20C service manual PDF" or "Panasonic GP41Z chassis service manual". If the exact model manual is not available, documentation for closely related models (such as the TX-21RX20C) or the GP41Z chassis itself will be highly compatible.

Typically +140V or +141V, which directly drives the flyback transformer and horizontal output transistor (HOT).
