You might running too much RGB point correction. Normalize all your RGB points and work the geometry adjustments.
What is your source to the projector and what resolution?

Hi Georg,
When I saw the topic description I immediately thought it would be another case of a distinct line running right across the very middle of the picture, as that is a common problem with the NEC's if too much "vertical linearity balance" is used. Having seen your pictures though, I'm not convinced as it appears on all 3 tubes, however it is worth looking at that first. Check the values you have currently for any vertical linearity balance and reset to neutral and observe any changes ( if any ).
I'm thinking it looks more like a streaking issue though, especially after seeing picture 1132. Try decreasing the BRIGHTNESS control and see if that helps. You might have to decrease it a lot to see if any change occurs. If it does help then I suspect there is an issue with the base WHITE BALANCE settings and THAT is not an easy task to perform.
Does the issue arise with a lower resolution ?
Cheers,
Russ
PS. I'm sure your English is better than my attempts would be to converse in your native language so I wouldn't be too concerned. You are doing fine

Thanks for your post!
I have all parameter reset!!! Include vertical linearity balance. Exept the color settings.
The Problem is all over red green und blue.
I have a oscilloscope what can i do?
I think it if very difficult to catch (trigger) with the oscilloscope.
You understand?
-Streaking-

I have yet to test them 
Greeting Georg
Vielen Dank für deinen Beitrag!
Ich habe alle Einstellungen zurückgestellt, außer die Farbeinstellungen.
Das Problem erstreckt sich über alle Farben rot, grün und blau.
Ich habe ein Ozilloskop, kann ich was messen?
Jedoch wird es serh schwierig sein, den Fehler zu triggern!

Wegen dem streaking muss ich noch deine Vorschläge ausprobieren.

Hello,
Both of Problems @ differently resolutions!
Ideas about? especially about the curved lines in the middle of the picture?
you see it on the first with horizontal full-hd tv-lines testpattern , it looks as 2 lines squeezing!
Georg
Deutsch:
beide Probleme bestehen mit unterschiedlichen Auflösungen
Ideen darüber? Vor allem über die verbogen Linien in der Bildmitte?
Es sieht so aus, als ob sich 2 Linien von dem Full-HD TV-Linien-testbild quetschen.
