Check C4511, I have a note that says slight ticking check that. Also the
resistance on the secondary outputs should measure more than 100K and the
15Vshould be more than 4K.

shorted HOT, bad pin driverQ4803, bad pin diode, bad pin caps. Changed all
caps [4] in power supply primary, chopper transistor , chopper IC, D4122
