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...
[PWD signal] After plug the AC cord into outlet, VP voltage appears on the base terminal of transistor Q3. When the VP exceeds 16 volts, Q3 is turned on by the differential voltage between base and emitter terminal of transistor Q3. Then the PWD signal goes to GND level and informes � Power ON � to the CPU. When the VP drops less than 16 volts, Q3 is turned off. Then the PWD goes high level since the PWD is pulled up to VDD. When the CPU receives � High � signal of PWD, CPU goes to � Power failure process �. Note : During plug the Ac cord into outlet, all voltages are supplied to the PCB. If you open the machine for repair, make sure plug off. [Location for voltage check points] Actual value on the E259-1 PCB (unitV)
