I have reviewed other flyback and I have seen that others have the name abl. So my question right now is the abl also called EHT or something like that? The flyback that has that configuration is the "jf0501 21123"
It is pin 10 named EHT! Thank you if you respond and I hope you understand!
THE ANSWER THAT Victor E SAID, is the best since he is right attached some images that I edited so that they see that on the phillips TV the TV has "EHT" instead of ABL, and its structure is the same, the flyback sucks after a few diodes and finally a coil and ends on pin 10 with a line called EHT. It is only the name that apparently changes greetings!

Eht ... abl?

Hello, not the ABL (Automatic Blanking Level), it is the automatic brightness control that works with the cathode intensity (IK), which regulates and protects the tube from excessive brightness by current.

hello colleagues well I agree with the colleague victor and the opinion of colleague Carlos Quiroga is right only that I lack a detail as the colleague victor comments that the abl signal originates from the flay back pin and according to the scenes of the images that are produced on the screen in the video of more brightness and less brightness will be controlled x the abl greetings to the colleagues present do not fight me hahaha greetings friends

IK or AKB also means automatic white adjustment and was imposed by the Sony brand in the 80's. Its function is to maintain the purity of white by automatically adjusting the values of rgb. The signal sampling is obtained from the outputs r, g, b and no of the flyback, as in the case of abl.saludos

It is not a fight, just the one who asked the question wanted information on the fly back pins and not what I did to each one as a reference so that he saw that they are different.

ABL (automatic brightness level) means automatic brightness level, that pin automatically controls the brightness on the screen and prevents the emission of x-rays.
EHT (extra high voltage) means extra high voltage and is responsible for accelerating the electrons to the screen, so the pin abl in some cases is called eht.
the ABL or EHT pin on some flybacks is the same, there begins the winding of
the extra high voltage, and is also used as mentioned above in the definition of abl. greetings

AND
Heat
Heater is filaments of the tube. Follow the circuit and you will see that it dies in the tube. In that flyback the pin abl is the 8 that we talked about from the beginning or not? EAT is the pacifier cable that goes to the tube, carries the 24 kv or less. I am not rude. I keep confusing fatness with swelling. Your ignorance of the flyback is scary.

Yes Miguel. Less than not think. They were going to send me to take the soup. Haha.
.a little humor.
