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.

6. Failures
A
� Depending on the types of errors, one of the following error messages will be displayed when the unit is turned on:
EEP ERR
1. Breakage or short-circuiting of the communication line to the EEPROM can be suspected. 2. A failure in the EEPROM can be suspected.
OC ERROR
B
� If "OC ERROR" is not displayed when the unit is turned on in Normal mode, short-circuiting of the speaker terminals can be suspected. � If "OC ERROR" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The line between one of the above digital amplifier ICs and the speaker terminals is short-circuited. 3. The XSD line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken.
OVERTEMP
C
� If "OVERTEMP" is not displayed when the unit is turned on in Normal mode, the unit is normal. (It is likely that this was a temporary temperature rise, lower the volume of the speakers.) � If "OVERTEMP" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the MAIN Assy is in failure. 2. The OTW line from one of the above digital amplifier ICs to the system-control IC (PDC128A) is short-circuited by grounding or is broken.
7. DSP error display
� Each time the SOUND key on the remote control unit is pressed while the power is on, the DSP error display and the normal display are alternately switched.
U TEST
8. Accumulated power-on time display and speaker setting display
� If the AUDIO INPUT key on the main unit is held pressed for 8 seconds while the power is on, the accumulated power-on time display and the speaker-setting display will be alternately switched at intervals of 3 seconds.

� Power-on time is always counted while the power is on, regardless of unit's functions and operations. However, it is not counted during Standby mode. � The maximum countable power-on time is 255H59M (255 hours 59 minutes.) The indication will not advance beyond that. � The accumulated power-on time basically cannot be cleared.
