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.

This comprehesive service maual was greatly appreciated, as was the digital download.
SECTION 3 SET-UP ADJUSTMENTS
� � The following adjustments should be made when a complete realignment is required or a new picture tube is installed. These adjustments should be performed with rated power supply voltage unless otherwise noted. Perform the adjustments in order as follows : 1. Beam Landing 2. Convergence 3. Focus 4. White Balance Note : Test Equipment Required. 1. Color-bar/Pattern Generator 2. Degausser 3. Oscilloscope
Controls and switch should be set as follows unless otherwise noted: PICTURE control ........................................................... normal BRIGHTNESS control ................................................... normal
.................................................................................................................................................................................................................................
Preparations : � In order to reduce the influence of geomagnetism on the set's picture tube, face it east or west. � Switch on the set's power and degauss with the degausser.
Purity control
3-1. BEAM LANDING
1. Input the white raster signal with the pattern generator. Contrast Brightness normal

Fig. 3-2
2. Set the pattern generator raster signal to green. 3. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 3-1 through 3-3.) 4. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-1.) 5. Switch the raster signal to blue, then to red and verify the condition. 6. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws. 7. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)
