Good friends I have this tv Phillips chsasis la03.02 the problem of this tv esque turns on and off .. Adjust the screen before it turned off and you see in the middle lines of colors on the screen. B + voltage is 95 in standby. And in 97 when turning on. Solve the entire plate. Clean. And nothing. Change filter 2465. That measured was fine. Change C2460 from 56nf. And nothing. Collector voltages of 7464 is 22V. Collector of 7465 is -13. All this voltages I think are correct. I miss it here, taking C2465 out completely and proceeding to turn on the screen is about 3 "open from the center of the screen and the TV does not turn off. It stays on is not protected. I need help. Orient me.

good xaviromer, check voltages in the jungle part at the vertical driver's output, take voltages in tr 7461, 7462, 7463 and 7466, without matching those in the diagram it could be the jungle that is damaged, measure those voltages Comment the results.

Tr7466 = C = 0.4, B = 0.4, E = 0.7.
Tr7463 = C = 0.7, B = -12, E = -14
Tr7462 = C = -12, B = 1.3, E = 1.2
Tr7461 = C = -13, B = 0.9, E = 1.4.
These are my measurements friend. That comparing them with the diagram are almost equal.

Place a new electrolytic. 10uf x 160v. And see what happens. The voltages are within parameters. here diagram. https://elektrotanya.com/philips_21pt3205_55-ch.l03.2l-aa.pdf/download.html

I already put another capacitor with the same new features.
And nothing .. I raise the screen you see the three inches of open with a lot of brightness and colored lines. But you don't see the channel number. And it goes out.
And when disconnected, remove the capacitor completely, the same 3 inches open with brightness appear. Without colored lines, but here you can see the channel number. And the tv does not turn off. What could be a friend? I don't know how to attach photos to see.

For the photos . Go to your question and below you have a pencil to edit it and then you have where to upload images.

Friend I tell you to change the yoke ... And the TV turned on perfect ... With exact picture .. Only it does not fill me on the sides of the screen. Connect the cable and give me the image upside down. How can I make you friends?

You are inverting the vertical retired cables.
