When repairing, use the following procedure for effective Self-diagnosis and tilt adjustment.Be sure to use the self-diagnosis functionbefore replacing the optical pickup when NO DISC is displayed. As a guideline, you should replace the optical pickup when the value of the laser drive current is more than 55. Note: Press the power button to turn on the power, and check the value within three minutes before the unit warms up. (Otherwise, the result will be incorrect.)

Confirm that J_xxx_yyy_zz is shown on the front display. For your information: yyy and zz shown to the right have nothing to do with the jitter value. yyy is the error counter, while zz is the focus drive value. Note: Jitter value appears on the front display. 3. Play test disc T01 (inner periphery). 4. Adjust tangential adjustment screw so that the jitter value is minimized. 5. Play test disc T43 (outer periphery). 6. Adjust tilt adjustment screw 1 so that the jitter value is minimized. 7. Play test disc T43 (outer periphery). 8. Adjust tilt adjustment screw 2 so that the jitter value is minimized. 9. Repeat adjusting tilt adjustment screws 1 and 2 alternately until the jitter value is minimized. TOP PREVIOUS NEXT http:/servis- 8.4.1.2 Important points TOP PREVIOUS NEXT 1. Make tangential adjustment first, and then make tilt adjustment. 2. Repeat adjusting two or three times to find the optimum point. 3. Finish the procedure with tilt adjustment. TOP PREVIOUS NEXT Jitter value depends on the model: 1.If the jitter value changes like B, the optimum point is easy to find. 2.If the jitter value changes like A, set the optimum point near the middle. http:/servis- 8.4.1.3 Check after adjustment TOP PREVIOUS NEXT Play test disc or any other disc to make sure there is no picture degradation in the inner, middle and outer peripheries, and no audio skipping. After adjustment is finished, lock each adjustment screw in position using screw lock.
