I Recently purchased yet another Service Manual from Owner-Manuals.com, this time for a Sony EVS700ES/UB Videocassette Recorder. The Manual was available for upload within two hours and is an Extremely Good copy, as some of this I was able to enlarge to get even better detail.
Once Again, Very happy with the result!
;
A good and useful manual. With these, We was abled to isolate and pin point the component that was causing the problem. The total time spent in troubleshooting is very much reduced.
;
The quality of the manual is top. The transfer worked perfect and fast.
No problems at all. Recommendable

3.3 Maintenance of laser pickup (1) Cleaning the pick up lens Before you replace the pick up, 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. � The level of RF output (EFM output:ampli tude of eye pattern) will be low.
3.4 Replacement of laser pickup
Turn off the power switch and, disconnect the power cord.
Replace the pickup with a normal one. (Refer to "Pickup Removal" on the previous page)
Is RF output 1.3 ±0.4Vp-p?
NO
Replace it. 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.
YES
O.K
(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 laser pickup may be damaged due to excessive current.
Play a disc.
Check the eye-pattern at RF Test Point.
Finish.
