I apologize.

The problem persists in a black strip on the right side of the TV
Shadow type now on certain channels such as that fault decreases and in video mode the screen is half black and half gray with vertical stripes medium light green

let's see, what tension do you have on the tube plate where it says 180 Volts

Hi tobias, I measure tension where you ask me I have 126v

What I am going to do is change the receiver if there is something changing but the diode marks me in good condition

That is your problem, you have to have 180 volts, notice that it comes from the flyback, goes through a low-value resistor, filters it in a capacitor and goes to the transistors of the tube, for me it is the electrolytic one, you can put one of 10 micros by 250 volts or the resistance that is before the diode

If tobias this is how decis works with that voltage now I change the components and I tell you the result capo thousand thanks for the help

Tobias told you that thanks to your guidance capo and solved the problem which was the resistance of low beacon of 1ohm which previously was measured and gave me ok.Now I replaced it to that resistance and the voltage raised to 190v which I seems a bit high

Thank you very much TobiasTV bonnet for the help and guide that persists in that stage of the 180v of the TV. By changing a r of 1ohm the image problem has been solved. Thanks bonnet.
