2300MP solid white blinking line...

When I turn on my Dell 2300MP projector it has a rapidly blinking white bar on the left side of the image. It happens no matter the connection. It goes away after about 5 minutes. I've replaced the bulb and even took it apart and dusted it according to this article

Has anyone had this problem and fixed it?

Thanks,
