PMP9608: UCC 28910 cannot start up

Part Number: PMP9608
Other Parts Discussed in Thread: UCC28910

Hi, 

I tried to follow reference design, PMP9608, but there was no +3.3V or -3.3V voltage generated. Here is the link of the reference design, 

. I used the same components in reference design. 

There was a high voltage generated (around10kHz) by Pin Drain of UCC28910 but there was no voltage between Pin 1 and 2 of transformer. It caused that no output voltages were from AUX side and secondary side. The votlage from Pin Drain was very high because it could be 1100 V when I used AC voltage channel of multi-meter to measure it (Vin was 120V AC). Is there anyone help me solve it? 

Thanks.
