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.

3-6. CONVERGENCE ADJUSTMENT
1. Input the dot pattern signal. Set CONTRAST to the position at which it can be seen clearly. Set BRIGHTNESS to MIN. 2. Align the R, G, B dots in the horizontal direction at the center of the screen using RV703 (H-STAT). Note: If H-CENT was changed after adjusting HSTAT, adjust H-STAT again. (The HSTAT can be changed by the H-CENT switch.) 3. Align the top and bottom of R, G, B at the center of the screen using the V-STAT (vertical static convergence) magnets. Note: After the V-STAT adjustment, always paint the magnets to lock.

5. For VMC, use a 6-pole magnet to adjust so that the R and B dots are symmetrical above and below the G dot.

(Bottom section)
6-pole magnet Perform the VMC adjustment by rotating the 6-pole magnet to the left and right without changing the opening of it.
Adjust so that the displacement of the dot is equal at the top and bottom.

6. Repeat steps 2 to 5 until the convergence becomes correct. Note: Adjusting the convergence may affect the landing. Therefore be sure to check the landing again after completing this adjustment. 7. After adjusting, paint each magnet to lock them.

V.STAT convergence magnet Purity BMC magnet
While maintaining the V-STAT magnet knobs A and B at the same angle (I = I'), adjust the top and bottom convergences. If A and B are asymmetrical (I = I'), it will have a negative effect; the focus may not be accurate, or the beam striking may occur. 4. For HMC, use a 6-pole magnet and adjust so that the R and B dots are symmetrical at the left and right sides in respect to the G dot.
