Re: Philips TV 272217100569 Power Supply No Standby
Are ther any markings or a letter/number on it? you may need to clean it with some alcohol. The ic's Vcc maximum is 20 volts so I would guess around 18 volt zener. Q101 supplies the Vcc to the other parts of the main and pfc circuits and it acts like a regulator/switch.It has a zener on its base of 15 volts so its collector would need about 18 volts to operate.
I found this similar circuit
