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.

A : PG DELAY
3. Why to adjust PG delay : To compensate mechanical tolerance by adjustment.
4. Concept of automatic adjustment To adjust 6.5H means to set the time from SW.P to V.Sync at 6.5H. We can do that by compensating the undesired time as long as we can check the time between the two. The micom check the gap between SW.P and V.Sync by resolution of 2 § �(1H à 64 usec ) . After comparing the checked time with actual 6.5H, the difference is compensated and then SW.P is output. With this kind of method, we can get the effect same as manual adjustment in the past. result is saved in an EEPROM so as to keep the data in spite of RESET mode. And also, all the
5. Process In Automatic adjustment mode, The micom makes progress to fix PG delay to 9.14 degree maximum range as controllable as, to get average time from to check SW.P and V.SYNC�s time be read from Tape as 4 times, to compensate the time equivalent to 6.5H. Under the time compensated condition, The micom makes recheck SW.P and V.SYNC�s time, if the result is in the range 6.5H ¡ ¾.0H, then the DATA will be saved to EEPROM, or not repeat this 1 process with adjusted state
