Great copy of the manual, has all information required for servicing,
;
I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.
CONVERGENCE ADJUSTMENTS NOTE: Before attempting any convergence adjustments, the receiver should be operated for at least fifteen minutes. s CENTER CONVERGENCE ADJUSTMENT 1. Use the cross-dot pattern from among the built-in test signals. 2. Set the brightness and contrast for well defined pattern. 3. Adjust two tabs of the 4-Pole Magnets to change the angle between them (See figure 2.) and superimpose red and blue vertical lines in the center area of the picture screen. 4. Turn the both tabs at the same time keeping the angle constant to superimpose red and blue horizontal lines at the center of the screen. 5. Adjust two tabs of 6-Pole Magnets to superimpose red/ blue line and green one. Adjusting the angle affects the vertical lines and rotating both magnets affects the horizontal lines. 6. Repeat adjustments 3, 4, 5 keeping in mind red, green and blue movement, because 4-Pole Magnets and 6-Pole Magnets have mutual interaction and make dot movement complex.

s CIRCUMFERENCE CONVERGENCE ADJUSTMENT 1. Loosen the clamping screw of deflection yoke slightly to allow the yoke to tilt. 2. Temporarily put a wedge as shown in figure 1. (Do not remove cover paper on adhesive part of the wedge.) 3. Tilt front of the deflection yoke up or down to obtain better convergence in circumference. (See figure 3.) Push the mounted wedge into the space between picture tube and the yoke to fix the yoke temporarily. 4. Put other wedge into bottom space and remove the cover paper to stick. 5. Tilt front of the yoke right or left to obtain better convergence in circumference. (See figure 3.) 6. Keep the yoke position and put another wedge in either upper space. Remove cover paper and stick the wedge on picture tube to fix the yoke. 7. Detach the temporarily mounted wedge and put it in another upper space. Stick it on picture tube to fix the yoke. 8. After fixing three wedges, recheck overall convergence. Tighten the screw firmly to fix the yoke and check the yoke is firm. 9. Stick three adhesive tapes on wedges as shown in figure 1.
