(2) Life of the laser diode When the life of the laser diode has expired, the following symptoms will appear. The level of RF output (EFM output:ampli tude of eye pattern) will be low. (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 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 laser diode is almost worn out, and the laser pickup should be replaced. If the semi-fixed resistor is adjusted while the pickup is functioning normally,the la- ser pickup may be damaged due to excessive current. 3.4 Replacement of laser pickup Is RF output 1.3 0.4Vp- p? YES NO O.K Replace it. Turn of the power switch and, disconnect the power cord. Replace the pickup with a normal one. (Refer to Pickup Removal on the previous page) Plug the power cord in, and turn the power on. At this time, check that the laser emits for about 3 seconds 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.
