Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

Received a quick response, material was exactly what it was supposed to be. The service did everything I expected it to do. would use service again.

Excellent service from Owner-Manuals.com, good prices and quick turn around. The supplied PDF was good enough quality to be enlarged sufficiently to read component values.
[Dynamic Convergence Adjustment] 1. Minimize the vertical misconvergence in the left-most end of the center of a screen and in the right-most end of the center of a screen by adjusting the DY correction reactor XCV as shown in Fig. 1-15. 2. Minimize the vertical misconvergence in the top of a screen and in the bottom of a screen by adjusting the DY correction reactor YCH as shown in Fig. 1-15. 3. Minimize the vertical misconvergence in the top of a screen and in the bottom of a screen by adjusting the DY correction reactor TLV as shown in Fig. 1-15. 4. Minimize the vertical misconvergence in the left-most end of the center of a screen and in the right-most end of the center of a screen by adjusting the DY correction reactor TLH as shown in Fig. 1-15.

[G2 Adjustment] 1. Connect the 480/60i entire black signal to the ANALOG Y/G input connector. 2. Connect an oscilloscope probe one after another to the C board R-cathode (TP701), G-cathode (TP702) then B-cathode (TP703) to measure the DC voltage at their respective pedestal portion. 3. Connect an oscilloscope to the cathode whose DC voltage of the respective pedestal portion has the highest DC voltage. 4. Adjust RV702 on the C board so that the DC voltage of the respective pedestal portion is 125 ± 3 V.
