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.

Servicing precautions 1. Protector Operation
This model is provided with five protector circuits. Below discussed are the behaviors and indications of these circuits. (Note: In some cases, the LED flashing cycle and possible trouble spot may be inconsistent.) 1 Over-current Protector Circuit: A rush current into the flyback transformer is detected. The circuit is activated if an over-current flows in. Indication: The power LED (red) flashes once. 2 X-Radiation Protector Circuit: This circuit is activated if the rectified heater voltage rises above its specified level. Indication: The power LED (red) flashes once.

4 +B Under-voltage Protector Circuit: The voltages at the 10V, 25V, 32V, -8V and -25V lines of the switching regulator are detected. The circuit is activated if any of the voltages drops below its specified level. 5 +B Over-voltage Protector Circuit: The voltages at the 10V, 25V, 32V and -25V lines are detected. The circuit is activated if any of the voltages rises above its specified level. Indication: The power LED (red) flashes three times.

2. Stop of Protector Operation
The protector may be kept inactive by opening the detection circuits or grounding C3230 and C3231 (on the Signal Unit). The vertical output protector circuit, however, cannot be made inactive. Note: Be sure to get the protector back to normal after servicing.
