This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

Good quality, all schematics of few of models. There is also short form of user manual and regulation manual.
;
Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

SECTION 3 SET-UP ADJUSTMENTS
� �
The following adjustments should be made when a complete realignment is required or a new picture tube is installed. These adjustments should be performed with rated power supply voltage unless otherwise noted.
Perform the adjustments in the following order : 1. Beam Landing 2. Convergence 3. Focus 4. White Balance Note : Test Equipment Required. 1. Color-bar/Pattern Generator 2. Degausser 3. Oscilloscope
Controls and switches should be set as follows unless otherwise noted: PICTURE control ........................................................... normal BRIGHTNESS control ................................................... normal
................................................................................................................................................................................................................................
Preparation : � In order to reduce the influence of geomagnetism on the set's � picture tube, face it east or west. Switch on the set's power and degauss with the degausser.
Neck assy DY
3-1. BEAM LANDING
1. Input a white signal with the pattern generator. Contrast normal Brightness
}
Note: Neck Assy is exactly behind DY (no gap between Neck Assy and DY)
2. Position neck assy as shown in Fig3-2. 3. Set the pattern generator raster signal to a green raster. 4. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 3-1 through 3-3.) 5. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-1.) 6. Switch the raster signal to blue, then to red and verify the condition. 7. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws and DY spacers. 8. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)
