Adjusting Method

Completion of control

- All adjustments need to be performed after for 1hour or more.
- Heat-run is executed in the state of non-signal noise.
- If a retrace line appears on the screen during heat-run, rotate the screen VR left and carry out

heat-run when it disappears.

- Note) If stop image is kept over 10 min, a fluorescent material of CRT can be damaged.

Step 1. Control of screen voltage

1) Press the S9 key of Service Remote Control when set’s on.
2) Select PICTURE OFF & VERTICAL OFF. After turning the screen VR of focus pack right,

slowly rotate it left when a horizontal line appears and fix it when the line disappears
completely.

3) Control Red VR, Green VR and Blue VR in the order.
4) Fix the VR by lock paint after the control is completed.

Note) This control should be performed in a darkroom.

Step 2. Control of P-Lens focus

1) Receive RETMA pattern.
2) Loose the fixing nut of lens.
3) Rotate the fixing nut of lens left and then right slowly. Fix the optimum focus position by

repeating this method.

Note 1) Control the focus on the basis of 6cm by 6cm (intra-office signal 8CH, No.3) at the

left bottom of the screen.

Note 2) Perform the focus readjustment or correction if the entire screen isn’t focused even

after the completion of focus control.
