LightCrafter 3000 don't work

In the experiment, at the first our DLP LightCrafter 3000 development kit was able generate a static image. But a moment later, the device stopped producing light. The Red/Green Led (D1) and Green Led (D5) on the system board (top board) went out and don’t blink. The Red LED (D3) on the driver board (bottom board) is blinking all the time.

When the kit was turned off via the SW1 on the driver board (bottom board), the Green LED (D2) flashes one time only. Then D3 is blinking all the time. Nothing else happens.

When the power (JP1) is applied again (via the recommended AC adapter), Nothing else still happens.
