Report "Our discovery wonderwall entertainment projector turns on fine and a light is on that I can see if I put it 6 inches from the wall in a dark room but there is no picture when I plug it into the dvd player, which has the 3 colored plugs to match. The dvd player is playing but there is no change in the projector. Is there some button I'm supposed to push to coordinate it with the dvd player and is there a way to "focus" it? turning the lense does nothing. Does it really work or is this a scam?"
