  If your BenQ Projector isn't turning on, there could be a couple of reasons. First, ensure the power cord is correctly plugged into both the projector's AC inlet and a functioning power outlet, and that the outlet switch is on. Alternatively, the projector might be in the process of cooling down from a previous use. If this is the case, wait for the cooling process to complete before attempting to turn it on again.

  Christina WoodAug 18, 2025
  A blurred image on your BenQ Projector can typically be attributed to two things. First, the projection lens may not be correctly focused, so adjust the focus using the focus ring. Second, the projector and the screen might not be properly aligned. In this case, adjust the projection angle, direction, and height of the projector as needed.
