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.

�� When "Fig. 1" screen is displayed, and if "OK" is clicked, "drive frequency and the motor control adjustment" is completed. If "Adjustment could not be executed." of "Fig. 2" is displayed, make readjustment. Even after the readjustment, if "Fig. 2" screen is still displayed, adjust the "MR duty" again and perform "drive frequency and the motor control adjustment" again. However, after all the above, if the adjustment is still impossible, the SWM unit, the fixed tube unit, GMR tape unit, or MR head unit may be defective.
