I also set it to zero, 355v, 400v at the maximum in any way it worked and I want to throw in the towel

No, you don't have to give up, I try to see if the screen voltage varies when the tube plate is disconnected? while the TV is on.

You checked if the diode 6318 of 8v2, is short, same as r3318 of 220 in the box that connects to the screen.

Hi. Exactly what filters you changed. Check if you don't put one upside down. I tell you just in case, many times that happens.
