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.

CD SECTION
Note: 1. Perform all CD section check in the CD Test Mode. (Refer to page 16) 2. Use the PATD-012 disc (Part No.: 4-225-203-01). 3. Use an oscilloscope with more than 10 M� impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.
Checking Location: � CD Board (Conductor Side) �
TRAVERSE CHECK
oscilloscope (DC range) CD board TP (TE) TP (VC) + �
TP (TE) TP (RF) TP (VC)
Procedure: 1. Connect an oscilloscope to TP (TE) and TP (VC) on the CD board. 2. Load the disc (PATD-012). 3. Press the three buttons of x , [MODE/DIR] and [CLOCK] simultaneously to enter the CD Test Mode and display �88� (Initial mode). 4. Press the CD u button to enter the FOCUS1 mode and display �F-�. 5. Confirm that the center level of waveform is 0 V. 6. Confirm that the Vp-p value of waveform is 0.35 to 1.1 V.
VOLT/DIV: 0.2 V (with the 10:1 probe in use) TIME/DIV : 1 ms

FOCUS BIAS CHECK
oscilloscope (AC range) CD board TP (RF) TP (VC) + �
Procedure: 1. Connect an oscilloscope to TP (RF) and TP (VC) on the CD board. 2. In the FOCUS1 mode, press the CD u button to enter the ALL SERVO mode and display �P-�. 3. Confirm that the oscilloscope waveform is as shown in the below figure. (eye pattern) A good eye pattern means that the diamond shape ��� in the center of the waveform can be clearly distinguished.
VOLT/DIV: 0.2 V (with the 10: 1 probe in use.) TIME/DIV: 200 ns
0.6 to 1.2 Vp-p
When observing the eye pattern, set the oscilloscope for AC range and raise vertical sensitivity.
