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.

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
BLOCK DIAGRAM DESCRIPTION
ATSC/NTSC tuner (TDVB-001P) can receive both terrestrial analog and terrestrial digital signals. But a NTSC tuner (6700NFNS06C) can receive terrestrial analog only. Therefore if you run two displays at the same time, it is not possible to see two digital channels. A/V SW (CXA2069) is the IC that takes external input terminal signals and broadcast signals from the tuners and handles them selectively. Audio signals are sent to MSP4450. Video signals are sent to HD-II via two paths - VPX3226E on the upper side is used to handle sub displays, while VPX3225E on the lower side controls the main display. To the lower side, signals are sent using an expensive 3D-comb filter with Y/C divided. The video decoder (VPX3226E) is a chip that decodes input signals. HD-II is a chip that controls nearly all video-related functions, including brightness, sharpness, video formatting and scaling. If digital broadcasting is available, it comes through TP, which can be controlled from HD-II. Video SW (CXA2151) is an IC that outputs video signals selectively. The selected one is outputted through ADC (AD9883A) as a digital signal. uCom (M37272) interfaces with the main CPU and primarily plays the role of controlling power supply, remote controller and timers. Thus, while the set is turned off, it sends time information to uCom for management. TMDS Tx (Sil164) is the display stage that sends video data to the display medium according to the TMDS protocol, and the TMSD receiver accepts it and outputs display. CPU (S3C440BX) is the central processing IC, which controls most of the ICs.
