BN44-00161 repairs

[netdent]

Need some guidance I repaired this psu, QX801 and 802 were blown apart, I replaced them but still no results, discovered  DX804 to be short or low ohms (11ohms in circuit) this smd diode/transistor is designated as B3 trawling the net I came up with this

but not sure if this is what I need?
