An output power problem for using the chip TPS54620 to drive the R G B LED

 Could someone tell me why the voltage of LED anode(R G B) can not reach 3.3V(I have measured the voltage RED_ANODE, and it's about 0.24V),according the PCB schematic designing which from  tidr157 DLP4500-C350REF Schematic on page 27 and 28 ?

I have checked the conditon of nets P12V_LD, P12V_CONN, P3P3V, and all of them is working good. The voltage of RED_LED_EN is 3.3V. When I connected the  Red LED through the connector J33, the LED could not give out light. Have anyone encounted this question, help me please.
