Hard to find manual was ready the next day. Scans were very legible (including schematics). All the essential parts of the service manual were present (adjustment procedure, schematics, and parts list). It would have been nice if the rest of the manual was included (disassembly procedure, theory of operation, etc.).
 ;
The Service Manual for the Kenwood KR-V55R provided by owner-manuals.com was as described/advertised. The contents provided the necessary information to effect a diagnosis of the unit. The schematics above all else was instrumental in tracing the the signal flow from component to component.
;
This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
;
Impeccable, document très complet. Perfect, i get all i need. All schematic are correct. Thanks

The manual is of better quality compared to other. I found it less expensive and therefore it it is the best buy cost vs quality.

2-2-1 White Balance Adjustment
1. W/B Adjustment is required for the following four modes: DVI � DTV � PC � CVBS(VIDEO) � CVBS(VIDEO PIP) 2. Adjustment Method (DVI, DTV, PC : VG828, CVBS : Adjust RF signals to match the Toshiba pattern (in-house signal) ! Adjust the target set by adjusting the panel logic and the video DNIe adjustment register in register in order to determine the referential W/B of the panel with a DVI input, which is the full digital path. @ For DTV adjustment, adjust the adjustment register of ad9888 to align the DTV signal to the DNIe and logic panel value which was fixed with a DVI adjustment so that they are in effect considered to be the same signals. (At this time, do not adjust the gain of AD9888 � the Highlight W/B does not need to be adjusted since its deviation falls within valid distribution range.) # PC adjustment is same as DTV adjustment. (The offset can be applied to the values obtained through DTV adjustment. However, additional adjustment is required for Y, Cb, and Cr of DTV since PC processes R, G, and B signals.) $ cvbs adjustment is performed with the Toshiba pattern (in-house signal) and differs from the VG828 signals in the above three modes. Hence, it should be performed with the same method of ! DVI adjustment. % Finally, activate PIP in video mode, and repeat W/B adjustment. � Thus, Micom saves the W/B data separately for each memory mode of the block (See the block diagram given below) during W/B adjustment.
Micom can memorize the four modes separately. However, under the current adjustment guidelines, DTV and PC are memorized with the same value during DVI adjustment and CVBS is memorized with a separate value.
