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.
ItΒ΄s very very nice manual with all, what i need. Original in good quality. Very fast business. Very much thanks...
Purchased the manual that I was looking for at a great price and could download it easily.. Great service experience and for future purchases I plan to use the site.
Thank you very much
SECTION 6 ELECTRICAL ADJUSTMENTS
Note: 1. Perform adjustments as given. 2. Power supply voltage: DC14.4 V (more than 3A).
â¢ TRACKING OFFSET CHECK â RF BOARD (Conductor Side) â
oscilloscope CNJ12 + â BP11 (TE) TP (VC)
â¢ FOCUS GAIN ADJUSTMENT (COARSE ADJUSTMENT) This adjustment is to be performed when replacing the following parts. â¢ Optical Pick-up Block â¢ RV14 â RF BOARD (Conductor Side) â
â¢ When gain is lowered... The set does not play because of no focus operation. â¢ When gain is highered... Operation noise is heard due to a scratch or a dust, then operation will be unstable.
â¢ FOCUS BIAS CHECK â RF BOARD (Conductor Side) â
oscilloscope CNJ12 TP (RF) + â
TP (VC) IC11
Procedure: 1. Connect the oscilloscope to BP11 (TE) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc. 3. Press the . AMS > button, and check the traverse waveform*. 4. Confirm that the oscilloscope waveform is symmetrical on the top and bottom in relation to 0 V dc, and check this level.
* Traverse waveform: This is the tracking error wave form appears when crossing the track.
Procedure: 1. Connect the oscilloscope to TP (RF) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc. 3. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
Note: Clear RF signal waveform means that the shape âââ can be clearly distinguished at the center of the waveform.
Procedure: 1. Set RV14 (RF board) to the standard position. 2. Check that there is not an abnormal amount of operation noise (white noise) from the 2-axis devise. If there is, turn RV14 slightly clockwise. â RF BOARD (Conductor Side) â
