Hi, you have no control because they broke it or because you simply don't have it. Because the control must be, it is more contained in the diagram.

Good, comment if you have any other modification, you have connected the cable that comes out fly back to the tube plate, lest the fly back pot is broken, and they put an alternative circuit that is to produce sgreen voltage

ready the problem was a dry capacitor of 22uf / 1000v was dry the detail that remained was that it looks with spots on the side of the screen

not having screen control as you indicate that is why it looks blended since it does not fit sceen, you have to look for another flayback that has those screen and focus controls or place a separate screen is something similar to this one that I leave in the image but it brings 2 controls to adjust

Well if it has no modification, you have to change fly back, there is no other, or make circuit that happened colleague and tests

The resistance comes out of the 180v of the fly back, verify diode and electrolytic that works with resistance, not what number did you say you had a bridge

I already solved it was a dry capacitor of 22uf / 1000v the only detail it has is are colored spots on the side of the screen

And the regulator of the sgreen that happened like this without it, had another modification or what?

The white screen problem was not the same. It was the bad capacitor. I thank everyone for shaking hands.

well I think that problem can be in the 411 resistance that goes to 200 v video

The R 411 = 2.2 x 2w, has audio TV, but if the fly back controller is missing, it is not right there
