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.

It´s very very nice manual with all, what i need. Original in good quality. Very fast business. Very much thanks...

CD SECTION
Note : 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use LUV-P01 (4-999-032-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M� 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. S-Curve Check
Oscilloscope BD board
Note: Clear RF signal waveform means that the shape ��� can be clearly distinguished at the center of the waveform.
VOLT/DIV : 200mV TIME/DIV : 500ns
level : 1.45 ± 0.3Vp-p
E-F Balance (1 Track jump) Check

TP(FE) TP(DVC)
TP(TE) TP(DVC)
Procedure : 1. Connect oscilloscope to TP (FE). 2. Connect between TP (FE) and TP (DVC ( 1.65 V)) by lead wire. 3. Press the \/1 button to turn the power ON. 4. Load a disc (LUV-P01) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search) 5. Confirm that the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2 ±0.5 Vp-p.
S-curve waveform symmetry
Procedure: 1. Connect oscilloscope to TP (TE) and TP (DVC) board. 2. Press the \/1 button to turn the power ON. 3. Load a disc (LUV-P01) and playback the number nine track. 4. Press the bB button. (Becomes the 1track jump mode.) 5. Confirm that the level B and A (DC voltage) on the oscilloscope waveform.
center of waveform B 0V A (DC voltage)
A within 4 ±1Vp-p B
B=1.3 ± 0.6Vp-p
Specified level: A � 100=less than � 22% B
symmetry
6. After check, remove the lead wire connected in step 2. Note : � Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. � Take sweep time as long as possible and light up the brightness to obtain best waveform. RF Level Check

Procedure : 1. Connect oscilloscope to TP (RFDC) and TP (RFAC). 2. Press the \/1 button to turn the power ON. 3. Load a disc (LUV-P01) and playback. 4. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
