Hantarex MTC900 Blur post traumatic capkit

[rom1]

Hi
My mtc900 monitor had recently its flyback out of service i
I had a old other one working but bad and I ordered a capkit on eBay.
I replaced all the capacitor concerned by the one supplied ones.
A colleague of me checked my work and it was ok as you can see in this first picture.


I mounted the chassis on the other tube where the other that was off.
The pict was jumping and blur.
I thought i cames from the tube so i decided to replace it to by the other which was working with this chassis.
And... same result
You can see it here :

The turnings (horizontal, vertical, neckboard blur) have no effects.
What is going on?
Could you please help me ?

what about the flyback focus? or readjusting the neck yolk for a better focus?

[rom1]

I turn the focus on the neckbeard without result.
The rings of the yoke have no action too.
A guy said me that perhaps the potentiometer of the neckbeard is out of service.
What do you think?

[computerfixerguy]

Did you replace the flyback yet?

[rom1]

@computerfixerguy  no i did not it is on. i got an image.

So i replaced the neckbeard and then...
The image is clear and no more blured, but...
No synchronisation :-(
The tunings at the back of the chassis have no effects :

Perhaps it is a problem of voltage, what do you think ?

some news :
A wire between 2 cards of the chassis (synchronization inverter) was deluged.
I got the focus and a very good image, but...

As I moved the cab to his place back et restarted it : the pict is totally blured, grrrrr !

I changed the tube, and the neckboard and everything is almost perfect.
Juts a trouble of width, not controlled by the good pot (RV20, pin cushion  in place of 18, width) a,d th epic is too straight.
But it is playable for now...
