Hi, I have a dream land DG-747 projector and I am having a problem with it. The problem i'm having is when I turn off the projector with the remote or button on the projector to turn it off. The lamp wont turn off, it goes black for a second, then turns white on the screen. The entire machine is off, the fans are off, no pic is showing, and the light on the top is red but the lamp remains on. I hope you can solve my problem.
