Power supply schematic for the Sony GE3B board with part number 1-881-774-11, provided as a PDF. The name does not state the television model, but the part number printed on the module identifies it. The diagram helps diagnose no-power and standby problems by following the primary rectifier, PFC, switching converter and secondary outputs, and it gives component values for replacement. Check that the 1-881-774-11 number on your board matches before relying on the circuit.
