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.

I bought the service-manual of the sony ICB-1020(an old transmitter-receiver) at "www.Owners-Manual.com", I found the service-manual for a fairly cheap price(in comparison with other sellers). I filled in some questions, payed the order with Ideal, and within 24 hours I had my service manual. I was very happy:In no time I had my service-manual and everything, but literally everything was noted down in the manual; the electronic scheme, the parts list, etcetera.
A very practical, reference-document.

Laser Current Check * Perform this check only when the laser is faulty. 1) Connect a digital multimeter across the resistor R541 (10 ohms). 2) Playback TCD-782 and check the DC voltage value of the 3) 4) digital multimeter. Check the SPEC VALUE specified on the label of pickup. Calculate the laser current (Iop) by diving the DC voltage value across R541 by the resistor value (R541 = 10 ohms). Check that the laser current (Iop) is SPEC VALUE ± 10 %.
