DLP4710EVM-LC: My DLP module doesn't start properly

The current phenomenon as the following goes:

I powered up the module, press the ON/OFF button, wait for 3 seconds and the lens will start to display,

Then the startup interface of the application will appear,

But the display will automatically turn off after about 2 seconds.

And here is phenomenon and order of LED lights

POWER UP:

D43 ON      INTZ(D57)ON

PRESS THE ON/OFF BUTTEN:

D43 OFF    INTZ(D57)OFF

D56 BRINK ONCE

D33 ON & Len start to display

Len turn off after about 2 sec

D33 OFF     D56 BRINK ONCE

D43 ON       INTZ(D57) ON

I have tried for many times but it still can not start working normally.

I also have tried to reprogram the module by the frimware on homepage, but it didn't work.
