THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR
;
Very Good! All the diagram are easy to read, and its complete.
;
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!
Pincushion Adjustment (D05)
Procedure: 1. Cover Red and Blue Lenses. 2. Apply a crosshatch pattern. 3. Set DAC D0F from 0 to 1 (disabling digital convergence). 4. Adjust DAC D05 (Pincushion) by pressing CH updown and confirm that size is 30±5mm at �A� (See Figure 33) �A�
9. Transfer lens cover from blue to red, so that blue is projected. 10. Adjust blue deflection coil until the horizontal center line matches the pattern of the grid and is leveled. 11. Adjust blue centering magnets until the monoscope pattern center is at the appropriate distance as indicated on Figure 34. 12. Enable digital convergence by changing DAC D0F from 1 to 0. 13. Following the adjustment, make sure that all deflection coils are pushed completely toward the CRT cones and that all screws are tightened.
Horizontal Size Adjustment (D03)
Figure 33. Pincushion Adjustment 5. If Trapezoid adjustment is required after this adjustment, perform trapezoid adjustment. 6. Enable digital convergence by changing DAC D0F from 1 to 0 and remove caps from lenses. This is the manual adjustment of horizontal size that is included in the automatic convergence adjustment. 1. Apply a monoscope pattern. 2. Set DAC D0F from 0 to 1 (disabling digital convergence). 3. Cover both red and blue lens. 4. In service mode, adjust H-Size DAC (D03) until the picture horizontal size is 5.0 ± 0.2 lines at left side of screen. 5. Enable digital convergence by changing DAC D0F from 1 to 0. 6. Remove lens covers.
Centering Magnets Adjustment
Procedures: 1. Apply a monoscope pattern. 2. Cover the red and blue lens so only the green lens is projecting the monoscope pattern. 3. Set DAC D0F from 0 to 1 (disabling digital convergence). 4. Loosen the deflection coil screw on the green CRT. 5. Adjust green deflection coil until the horizontal center line is in line with the grid and is leveled. 6. Adjust centering magnets until the green pattern is equal on left and right. Adjust also for horizontal and vertical tilt.
Convergence Adjustment
Note: It is strongly recommended to first read and understand the following section prior to make any adjustment.
Turn PTV on and allow it to warm up for 30 minutes prior to making adjustments (WHITE PATTERN).
Note: This PTV uses the scheme described below to correct for misconvergence of the three CRT projection tubes. There are various modes to this operation.
Preparation: Place the Convergence Alignment Template (see �Convergence Alignment Template� on page 24) over the PTV screen. Align the center lines of the template with the mechanical center markers on the PTV screen frame. If the template is not available, create one using the dimensions provided in �Convergence Alignment Template� on page 24. Remote control must be used during the procedure.
Note: Push deflection coil to top of CRT neck, then tighten deflection screw after adjusting each CRT centering and Tilt.
7. Transfer lens cover from red to green and project red only. Adjust deflection coil until the horizontal center line matches the pattern of the grid and is leveled. 8. Adjust red centering magnets until the monoscope pattern center is at the appropriate distance as indicated on Figure 34.

Note:
Apply the Convergence Alignment Template to the PTV screen frame to converge the Green Raster only. Remove the Convergence Alignment Template following this alignment. The red and blue rasters can then be aligned to the green raster.
