If your BenQ SP890 projector is not turning on, check if the power cable is securely connected. Ensure that the power outlet is functional. If the problem persists, try a different power cable and contact BenQ support if necessary.
A blurry image can be due to incorrect focus settings. Adjust the focus ring on the projector's lens until the image is clear. Ensure the projector is at the correct distance from the screen according to the user manual.
