DS1 LED blinking on connecting power cable

I have run into a powerup issue with my AD96 ToF camera board. On connecting the power cable, previously the DS1 LED would light up indicating power up. But now I see its only blinking and the light on the power cable adaptor goes off immediately and starts blinking on connecting to the camera board.

Is this an indication of a power connection breakdown on the AFE board? how can this be checked?
