help tek 475 power supply

hello everyone after changing the electrolytic capacitors on my teak 475 I have a problem that turned on after a few minutes it turns off I checked that the transistor Q1446 2n2222 was defective due to the fact that it looks like a 24v zener diode with a 180 series resistor hom that heats up and makes you break some ideas?
