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.

7.1.6 TROUBLE SHOOTING
No.
1
Symptoms
The power is not turned on.
Diagnosis Contents
Check the voltage of AT+3.3V, �28V and FLDC on the POWER SUPPLY Unit. Are wires of output connector (POWER PCB ASSY) and CP4003 (DVDM Assy) disconnected or damaged ?
Possible Defective Points
POWER PCB ASSY Connector / cable
A
OPERATION 2 Assy Check that the voltage at IC651-pin 10 (K 1) on the FLKY Assy Tact SW becomes about 2.7V when the POWER key is pressed and 0 V when it (when operation of only the is released. POWER key on the main unit is not accepted) FLKY Assy Check that the voltage at OS651-pin 1 (IR) on the OPERATION1 Assy Remote receiver section (when operation of only the is in the range between 0 and 3.3 V while receiving signals from the remote control unit when any key on it is pressed. POWER key on the remote control unit is not accepted) 2 An opening screen is not displayed on the monitor � Check the voltage of E+6.8V and SW+3.3V on the POWER SUPPLY (The FL display lights. The Unit. POWER SUPPLY Unit mechanism does not work.) � Check the voltage of P.ON-H is about 2.8V on the POWER SUPPLY Unit. DVD MT PCB Assy 1.8V Regulator IC (IC4006)
C
B
Check that the following voltage are output : IC4006-pin 5 : 1.8V, on the DVD MT PCB Assy.
Is a resonator (X4001 : 27MHz) on the DVDM Assy oscillating ? � Is a signal input into IC4004-pin26 (PCE#) on the DVDM Assy ? (Is a signal "H" for 80 mS and then "L" after the power is turned on ?) � Communication with flash ROM. � Are the signals input into IC4005-pin 16 (DWE#), pin 19 (DCS#) and pin 38 (SDCLK) on the DVDM Assy ? (Is a signal fluctuating ?) � Communication with SDRAM
DVD MT PCB Assy Crystal resonator (X4001)
DVD MT PCB Assy DVD IC (IC4002) Flash ROM (IC4004) SDRAM (IC4005)
Is a signal output from IC4004-pin 28 (PRD#) on the DVD MT Assy? (Is a signal fluctuating for several hundred mS after the power is turned DVD MT PCB Assy Flash ROM (IC4004) on ?) Are the signals of IC4001-pin 5(SDA) and pin 6(SCL) on the DVDM Assy fluctuating for one or two seconds after the power is turned ? 3 An opening screen is not displayed on the monitor Check the video signal path between DVD IC (DVD MT Assy IC4002) (The FL display lights. The and video-out terminal (see the block diagram) mechanism does not work.) DVD MT PCB Assy EEPROM (IC4001) DVD MT PCB Assy Video circuit after DVD IC (IC4002)
