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.

TROUBLE SHOOTING TABLE (Continued)
Checking the output PWB unit
Are there signal inputs at No SC1404, SC1405, SC1501 and SC1502? Are voltages applied to EA connectors and SC5502? If there is no signal at EA
No
If there is no signal at SC1501 and SC1502, go to the video system block.
If there is no signal at SC1404 and SC1405, go to "Trouble shooting table for PC I/F unit".
Yes
connectorthe power unitblock. Checking or SC5502, go to
Are there signal outputs at pins (14) ,(16) and (18) of IC1401 ?
No
Yes
Check IC1401 and their peripheral circuits.
Are there signal inputs at pin (47) of IC1101, IC1201 and IC1301?
No
Yes
Check IC1401 and their peripheral circuits.
Are there signal outputs at pins (17), (19), (21), (27), (29) and (31) of IC1101, IC1201 and IC1301?
No
Yes
Check IC1101,IC1201,IC1301 and their peripheral circuits.
Are there signal outputs at pins (17), (19), (21), (27), (29) and (31) of IC1102, IC1202 and IC1302?
No
Yes
Check IC1102,IC1202,IC1302 and their peripheral circuits.
No
If there is no signal input at pins (1) and (31) of SC1101, SC1102 and SC1103, check the switching circuit and amplifier circuit of IC1101, IC1201, IC1301, IC1102, IC1202, IC1302 and their peripheral circuits.
Are there signal inputs at SC1101, SC1201 and SC1301? Yes Yes
No
Check the R, G and B panels.
If there is no signal input at pins (15) and (30) of SC1101, SC1102 and SC1103, check IC1409 and their peripheral circuits.
Check IC1406, IC1407, IC1408 and their peripheral circuits.
