Tried to swap defl/conv coils red <--> blue. The issue remain to red. This post is confusing the hell out of me. Does it mean that you changed the yokes between red and blue and that still the red tube did not react on the bow? |

So my question is 1 When you change the convergence connector on the frame board between red and blue does the issue shift? 2 When you change the convergence connector on the frame board between red and green does the issue shift. Pleas answer these two questions with a simpel yes or no. 1 - impossible to do this test because the harness aren't lenght enough. 2 - yes |

What was the answer when you exchanged the complet yokes? repairalmostanything.com/post/5006post 5006 |

What was the answer when you exchanged the complet yokes? repairalmostanything.com/post/5006post 5006 When I said "swap complete yokes" intended that I had removed the tubes blue and red and swap ALL yokes placed on the tubes. Defl/conv and focus yokes of the red tube on the blue and vice versa. |

Yes ok I got that. But do you say that after swapping as described above the red tube still did not react on the bow?
I have to ask again and again because that would seem very contradicting.
What does 'The issue remain to red' mean?
1-the issue remain on the red tube
2-the issue remain with the red yokes

Ok no answer. If someone else wants to clear thing up please do so.

I said that the issue no fix swapping whole yokes.
So the issue not is in the yokes or his harness because after swap is always the red grid that no follow the green in N/S adjustments.

Ok I get it. You swapped the yokes between red and blue AND you swapped the connections on the frame board. The last part you did not say and got me confused.
So in fact you ended up with only changing the yokes of red to the blue tube connecting to the blue connectors on the frame. So that excluded the complete yoke and harness as you write.
Now we have to conclude that your convergence output board seems the problem but that is very strange that is why I kept asking for clarification of other strange stuff. At this point I do not understand what could explain this.

Negative test Redfox I tried to swap lines vertical of the blue and red. I tried to swap horizontal lines also, no change. The issue remain always to red. So the problem is to the convergences board. Correct? After you swapped red and blue did you realise that you had to use blue controlls in the software? i mean you have to do blue convergence in the menu to now correct red! Did you realise that? It is my understanding that the N/S Bow and Key are a global adjustment and are only adjustable with the green controls which then affects all 3 grids, right? |

Just to be sure that we are on the right track. Could you change RV with BV in the cable that connects the controller with the convergence board? That should shift the problem to blue. It requires to cut the yellow cable. You can repair that with some tape or shrinking stuff if you know what I mean. Pin 1 and pin 5 J571 That is the best I have at this point. Negative test Redfox I tried to swap lines vertical of the blue and red.I tried to swap horizontal lines also, no change. The issue remain always to red. So the problem is to the convergences board. Correct? Just to clarify the underlined statement above that the wires that were swapped were of J571, correct? From controller to convergence board. |

If the answer to my above post is correct then I would do a couple tests on the convergence board with my DMM.
With projector turned off and unplugged, disconnect J571 on the convergence board. Set DMM to diode scale. Put the negative probe on pin 6 of connector J571 and with the positive probe test pins 1,3 and 5 and give me those 3 readings.

It is my understanding that the N/S Bow and Key are a global adjustment and are only adjustable with the green controls which then affects all 3 grids, right? Yes, correct! When calibrate geometry in the top and bottom key/bow the projector show only green because red and blue must follow the reference green. I tried to swap all harness (there are three harness for each tube) one by one between red and near green. I noticed that swapping convergence harness the issue of red change in green. |

... at first, assuming a problem of at one harness, I swap whole yokes between red and two tubes.
The issue don't move in blue, so the harness are good.
