Roger, if your contrast (sometimes called picture) and brightness controls are at max you can increase the tubes brightness by turning the "screen control" clockwise, be advised a little turn goes a long ways, don`t crank it too far or you will get retrace lines, you will have to remove the back from the set and follow the red wire down from the tube to the "flyback transformer" on the front of the flyback are 2 controls, focus and screen, do not move the focus control, this should fix your problem.

Dark image


Flyback transformers usually have 2 adjustable rods - 1 is for focus the other is for screen (G2) voltage. try turning Clockwise the Screen adjust with brightness-contrast at max. Till you see white diagonal lines, then go back until the lines disappear - then tune the brightness to your desired level.
