Hi Got my system up and running but have a concern. When the projector is in standby, there is a little red LED inside the box that flashes slowly on and off. You can't see it from the outside, and the external standby LED is steady. Is this the LED of death, or something normal? It also makes a slight buzz, like a monitor does. Hardly audible, but its right above my head and annoys me at night. Do I live with it for the sake of leaving the power on, or risk switching on and off at the mains each time?
