My projector is not triggering the screen to drop. How do I test the trigger to ensure that the screen is not the issue?

By exposing the red and green wires of the provided trigger, connect a 9-volt battery to the bare wires according to their polarity with the screen plugged in to the wall outlet. Once the wires make contact with the battery’s terminals, the screen will drop. Releasing the voltage from the battery will make the screen rise automatically. This indicates that the trigger and screen are functioning properly. Please check with your power source’s manufacturer for further assistance.   If the screen does not drop when applying the voltage with the battery, the next step would be to test the screen’s circuit board. Do this by plugging in the provided wall box and pressing the DOWN button. If the screen drops, then you may need a replacement trigger.
