It sounds like the issue you're experiencing with the NEC NP-PX803UL-BK projector might be related to the lens mounting or alignment. When the projector is moved, it's possible that the lens is not properly secured or aligned, resulting in a loss of image. Here are a few steps you can take to troubleshoot this issue:

1. Check the lens mounting: Make sure that the lens is securely attached to the projector and that it is properly aligned. If the lens is not aligned correctly, it can cause the image to go black or become distorted when the projector is moved.

2. Clean the lens: It's also a good idea to clean the lens to ensure that there is no dust or debris obstructing the image. Use a soft, lint-free cloth to gently clean the lens.

3. Check the input source: Verify that the input source (such as a laptop, DVD player, or other device) is properly connected to the projector and that the source is working correctly.

4. Reset the projector: Sometimes resetting the projector to its factory settings can resolve issues related to image display. Refer to the projector's manual for instructions on how to perform a reset.

If you've gone through these steps and are still experiencing the issue, it may be best to reach out to NEC's customer support for further assistance.

If the image on your NEC NP-PX803UL-BK projector goes black once you move the projector, it is likely that the lens is loose. The lens is a delicate component, and it can be easily jostled out of place if the projector is moved. If the lens is not properly seated, it will block the light from the projector lamp, causing the image to go black.

To fix this issue, you will need to carefully remove the lens and then reseat it. Here are the steps on how to do this:

Unplug the projector from the power outlet.

Locate the lens release button on the projector. The lens release button is typically located on the side of the projector, near the lens.

Press and hold the lens release button while gently pulling on the lens to remove it from the projector.

Inspect the lens for any damage. If the lens is cracked or chipped, it will need to be replaced.

Carefully align the lens with the projector mount and gently press it into place.

Release the lens release button.

Plug the projector back into the power outlet and turn it on.

If the image is still black after reseating the lens, there may be another issue with the projector. You may need to take the projector to a qualified repair technician to have it serviced.

Here are some tips to prevent lens problems in the future:

Be careful when moving the projector.

Do not drop the projector.

Do not touch the lens.

Clean the lens regularly with a soft, lint-free cloth.

Store the projector in a safe place, away from dust and moisture.

I hope this helps! Let me know if you have any other questions.
