60% - 70%.

Adjustment Procedure

1. Short the 2-pin subminiature connector(s) on the appropriate CRT board to
remove the colors not being adjusted in order to adjust one color at a time.
The colors may be adjusted in any order.

2. Refer to the Lens Assembly Diagram. Loosen the fixing screw on the lens
assembly so that the lens cylinder can be turned. Take care not to loosen
the screw too much, as that could cause movement of the lens cylinder when
tightening.

Display Lens Assembly Diagram

3. Rotate the cylinder back and forth while observing the crosshatch pattern
at the center of the screen to obtain the best focus point. In order to
access the focus rings on the lenses, first remove the upper and lower back
covers, then remove the cross piece which is secured with four screws.
Replace the upper back cover to which the mirror is mounted. The small
opening allows access the focus rings.

4. After completing the optical focus, tighten the fixing screw.

5. Repeat the process for each of the other colors. Use care when adjusting
the green optical focus, as green is the most dominant gun and any error
will be easily seen.

6. After the adjustment is complete, replace the cross piece and back
covers, then repeat the Electrical Focus Adjustment if necessary.



Static Focus Adjustment

Adjustment Preparation

1. The preheat run should be complete.

Adjustment Procedure

1. Short the 2-pin subminiature connector(s) on the appropriate CRT board to

> chassis) Here is his info as told to me:
> "Came in with resistor RK54 burnt. He replaced that along with blue
> convergence IC IK05. When going thru auto convergence, TV does not
> respond, but RK54 stays good (auto convergence called Intellisense)
> On the converg. module,push "service only" button, crosshatch
> appears.Need to knowof any way to converge,or if a problem still exists
> with convergence board, Checking on a service manual, need desparately."
> I guess he is askingithat since he replaced the burnt resistor and
> associated blue converg. STK IC, is he not accessing the convergence
> alignment area pproperly, or is there an actual problem. he says the
> Intellisense doesn't appear to work.All I have.
