Perhaps very bad astig magnet adjustments?

No it's impossibile that's a astig. issue

Tried to swap defl/conv coils red <--> blue. The issue remain to red. Did you swap the actual coils or did you swap the wire harnesses to the coils? |

I mean, I know there is a language barrier here and you have to translate everything we say......... but is the translator really that bad? You do things completely different then what is suggested to do and then expect us to have the answers. It does not work that way. Unless you can find a proper translator then I may have to drop out of this project. |

Yes ... for me it is very difficult to understand quickly. There are many technical terms and easily confuse one thing to the other. You want to tell those little coils on the motherboard? In the picture below is label L83. They are swappable? In 808 they are not swappable. In the 1209s they are not on the motherboard.  |

Perhaps very bad astig magnet adjustments? Its either be the convergence board or the system board, swapping the green and red connections between system board and convergence board should tell which is at fault. |

When you say "system board" intend motherboard (in service manual named "frame")?

If you swap them there and the blue is now distorted, its either the cable, or its the CPU board. I doubt it will be the cable.
If it still remains on the red, the problem will be either the convergence board or the connections between there and the yoke.
Very good chance it will be the CPU board.

I hope that it is neither the board of convergences or cpu because they are the boards that I've just changed. |

Tried to swap the cable "to conv coil red" and "to conv coil green". But in this condition I can try only to check convergenge green to red.
The vertical shift (horizontal lines) are insufficient to cover green to red.
No problem for horizontal shift (vertical lines).
I exclude problems with cables because yesterday I tried to swap red/blue yokes and the issue remain to red.

Yes tomorrow I'll post a sshot Below some screenshots No convergence  blue + red  Corners blue + red     green to red  Corners green to red     blue to green  |

The vertical shift values (horizontal lines) of convergence red are extreme.
