 Adjustments

Yoke - 36

 

±

 

  Because you 

must make yoke adjustments 

from the rear of the 

computer, use a mirror to 

view the computer screen. 

Do not reach around the 

computer to adjust collars 

and rings.

 

  If you replace the 

CRT, you will probably need 

to adjust the yoke.
1 Using an insulated 

Philips screwdriver, 

loosen the yoke clamp 

screw two or three 

turns.
