Turn set on then off. Press & power buttons together.
Set R, G, & B bias controls to MIN
Set R, G, & B to MAX
Set Screen ( G-2) to just get a line.
Adjust 2 of the 3 BIAS controls for a white line.
Press power to get out of service.
Set Brite & contrast to max.
Adjust the R, B, & G DRIVE for best brite whites.
Probably best to mark the controls before starting. Also with age
you may have to compromise some by not running it to the max.
