Is this a bad CRT? 10BP4

[Kevin Kuehn]

Try turning your room lighting off. Next turn down the TV's brightness control, and see if the picture(contrast) control can give you a more defined with better contrast picture. With the brightness turned down you may get better focus control too. Keep in mind you can't increase screen blackness with the TV's controls unless the ambient room lighting is low. Think of it as a movie projected on a screen, and if you bring the room lights up too bright you loose picture contrast. These early CRT's were never intended to be viewed in a well lit room.
