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

FOCUS BIAS CHECK
1. Connect the oscilloscope to TP (RF) and TP (GND) on the CD board. 2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01) 3. Press the u (CD) button. 4. Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) A good eye pattern means that the diamond shape (�) in the center of the waveform can be clearly distinguished. � RF signal reference waveform (eye pattern)

T1 AM IF Adjustment
1. Set to power off state. 2. Connect a digital voltmeter to TP (DIMMER) and TP (GND) on the LCD board and confirm that the voltage is 0 V. 3. Turn on the power. 4. Connect the digital voltmeter to TP (DIMMER) and TP (GND) on the LCD board and adjust RV401 so that the voltage becomes 1.5 ± 0.05 V. 5. Turn off the power. 6. Applied sufficient light to IC403 (brightness sensor) on the DIMMER board and confirm that the voltage is 3.3 ± 0.3 V. 7. Short the BP404. Adjustment Location: � LCD BOARD (Component Side) �
