(3) Semi-fixed resistor on the APC PC board The semi-fixed resistor on the APC printed circuit board which is attached to the pickup is used to adjust the laser power.Since this adjustment should be performed

10、 to match the characteristics of the whole optical block, do not touch the semi-fixed resistor. If the laser power is lower than the specified value, the la- ser diode is almost worn out, and the laser pickup should be replaced. If the semi-fixed resistor is adjusted while the pickup is functioning

11、normally, the laser pickup may be damaged due to excessive current. 5.6Replacement of laser pickup Is RF output 1.0 0.35Vp-p? Replace it. NO YES O.K Turn off the power switch and,disconnect the power cord from the ac outlet. Replace the pickup with a normal one.(Refer to Pickup Removal on the previo

12、us page) Plug the power cord in,and turn the power on. At this time,check that the laser emits for about 3seconds and the objective lens moves up and down. Note: Do not observe the laser beam directly. Play a disc. Check the eye-pattern at RF test point. Finish. (No.49876)1-29 (No.49876) AV & MULTIM
