Top class product, I printed it out on A3 paper and it is clear and very easy to follow.
Cheaper than buying a new radio!
 ;
is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components
 ;
Hello.

Maintenance of laser pickup
5.3
Replacement of laser pickup
(1) Cleaning the pickup lens Before you replace the pickup, please try to clean the lens with a alcohol soaked cotton swab. (2) Life of the laser diode When the life of the laser diode has expired, the following symptoms will appear.
Turn of the power switch and, disconnect the power cord.
Is RF output 0.9 0.22Vp-p?
NO Replace it.
Replace the pickup with a normal one. (Refer to "Pickup Removal" on the previous page)
YES O.K
(3) The level of RF output (EFM output, amplitude of eye pattern: pin5 of IC601) will be low. (4) 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 laser pickup may be damaged due to excessive current.
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 5pin of IC601.
Finish.
