Symptom: TV is dead. No standby light.

Using the Schematic:

The schematic typically reveals a unified power architecture. Unlike older TVs with separate power boards, many TPV boards integrate the power supply unit (PSU) or rely on a specific voltage input (usually 12V or 24V from an external adapter).
