It's complete and helpful manual with good quality of scan. Thanks very much.

The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.

Exactly what was needed to assess the product - excellent value and great service
YH Adjustment (VR2 for vertical dynamic convergence) 1. Apply a crosshatch pattern. 2. Adjust contrast and brightness customer controls to obtain a correct picture. 3. With a driver Adjust VR2 (located in deflection yoke board Fig. 19) to obtain a proper corvergence at left and right side of the screen. (see Fig. 14)
Permalloy convergence corrector strip (part No. 0FMK014ZZ)
This strip is used in some sets to match the yoke and CRT for optimum convergence. If the yoke or CRT is replaced, the strip may not be required. First converge the set without the strip and observe the corners. If correction is needed: 1. Place strip between CRT and yoke, in quadrant needing correction. Slowly move it around for desired results. 2. Press adhesive tightly to the CRT and secure with tape.
DAF adjustment
Preparation: 1. Apply a crosshatch pattern. 2. Set user controls, bright to center and picture to max. 3. Connect a frequency counter to TPD10. Procedure: 1. Connect channel one of the oscilloscope with 100x1 probe to TPP33 (pin-1 T1551). 2. Connect channel two of the oscilloscope with 10x1 probe to CRT HEATER (L-Board). 3. Adjust �HDAFP� so both waves are in the same position. 4. Adjust �HDAFW� so TPP33 is 1.5 ± 0.5kVpp.
