Hard to see video played on decal actor

Hello everyone,

I know this is a lighting issue but don’t really know how to fix it. First of all I am trying to play a video via decal actor, the video is black and white. The room itself needs to be dark for a art gallery concept. The only space in the room lit is on the interior of the dome, so I have a point light sphere because the spot light for whatever reason will not show after a light build (it doesn’t even have a red “x” over it and the intensity was cranked all the way up). The point light will work prior to light build but once I have built the light the dome appears to be a black hole. If I move the point light slightly then the decal video will show up. What needs to be done so the decal is visible after the light built without moving the light?
