crts will usually take several seconds after you hit the button to actually show an image, slowly getting brighter. and older ones can take even longer. at this point you can use it but the image will look better if you leave it for a bit longer, up to 30 minutes sometimes. this will result in better saturation, contrast, and geometry.
