Excellent service manual, the only known point of note is the alignment of improvability scanned pages within the pdf page. The resolution is good.

Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.
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.

XV Adjustment (precise adjustment)
1. Apply a crosshatch pattern. 2. Adjust contrast and brightness customer controls to obtain a correct picture. 3. With a driver adjust the coil located in deflection yoke board to obtain a proper convergence horizontally.

Note:
Apply a red pattern and confirm purity, if purity is poor, repeat purity adjustments.
