LNK364PN Power supply cannot work

hi,dear pi engineer.recently, i am using LNK364PN chip for my power supply.
and my output is dual +5v, load is about 500ma.but it cannt work.
and the voltage of the drain cannot achieve 0v, the lower level is about 120V,
i use biasing feedback which connects to the FB pin, and the voltage is about 1.65V. and the BYPASS pin voltage is about 6.10v.
i donnt know why, can somebody make any suggestions? thanks.

the problem is solved. anyway, thank u.
ok

Could you please post your schematic and transformer design documentation?
Di you design your transformer using PI expert?
