    Your mirrors might not be aligned or dirty. Put a small peace of plywood in front of the tube and press the fire button. Next test after the first mirror and so on. Use the included orange plastic gauge to set the correct distance.

    The tube should be a light pink. Test at 99%.

    My guess is that you "over drove" your tube/power supply and killed the tube. Very common with these machines if you ran it at 65% power or more, due to the fact the tube's rating is not truthful. Fortunately for you, you just received your machine so it will be covered under warranty or you just do a chargeback on your credit card.
