Hi Tobias, thank you very much for answering. That EW transistor can be a big one with a big heatsink, does it have the acronym C5801 826?

it seems to me that no, that must be the hurizontal exit look if there is no other one size less size

Is it an arcade, what nostalgia, hahahaha what integrated do you use? of jungle or oscillator, take a good picture of the chassis so theorized;)

I was looking for that transistor and it says it's horizontal, I don't know how to add photos. But I don't see the jungle.
PD: a terrible nostalgia, that's why I want to make it optimal.

save the photos to your computer, go to the pencil in your question and add the photos from the clip
Of course, you do not need a jungle, you must have a video ic with horizontal and vertical oscillators, I asked you for the integrated one because maybe we will find the application circuit or another TV that uses it in order to guide us, you understand? :)

There I edited and added the photos. You say that from the preset there is no way?

I saw them but not what you want, the tda9102 is the oscillator but it does not have a peicushion ... it has many capacitors in the horizontal, I will see that from the collector of the C5801 and there are two mass-filled fat-colored capacitors between these two capacitors there must be a transistor that's it, I didn't see it in the photos ... :( or a photo of the screen failing either I saw

I added one more photo with the screen image. I understand tomorrow I look for the transistor in question, tomorrow I see if I can take a picture that looks good all the chassis. Thank you very much once again.

If it is a version of Tetris, not the best but zafable. One more query the collector of the C5801 is the central pin right?

H-Center = horizontal centering
, H-Hold = horizontal frequency
, V-Hold = vertical frequency
V-lin = vertical linearity
you need Vertical Sise, it has to be, it's vertical height, are you sure you don't have any more adjustments?

yes, it's the central pin

If you have others on a separate plate, with a flat cable comes out of the chassis and has I think there are 6 more. Tomorrow I detail what they are exactly.

Hi Tobias. In the chassis I saw two preset / potentiometers plus one says PIN and another one looks like it says SUB- and I don't see what it says at the end.
The pcb that has apart from the chassis say:
H-POSI
V-SIZE
V-SIZE
CONT
BRT.
That is all I see.

mark how is the one that says pin and move it a little for one side and a little for the other, if it does not fit leave it as it was. pin sounds like pincushion

Sorry Tobias delay, I tried to do it without removing the chassis from the structure, but it has a cage that adheres it to the tube and I did not have time to remove it. Tomorrow I hope to do it, I comment how it was. Thanks once again.

Trankilo, only life limits us, hahahahaha, mmm I don't know if I unsubscribe, they didn't give me a like :(
