Also take D3 out and measure it out of circuit. There is a dead short in the hot (AC input) section of the PSU. If something measures funny in circuit, take the component out and measure it again out of circuit.
What is printed on U1?
Marking on U1 - LNK304PN.

Marking on D3 - 8G 28Y. I google but don't seems to find any info this part. This should be a regular diode measuring ~700ohm like the rests of D1,2,4?
