motorollin is right, I have had a toastscan for about a year and it takes anywhere between 30 seconds and one min. to warm up properly. (I am using a 400watt ATX power supply) During this "warm up" time the screen will jump around a fare bit and may go on and off (this is normal). If the picture seems soft or fuzzy after this there is a small adjustment screw located on the side of the Toastscan by the sVGA out, turn that and it should clear up.
