Absence of video on TV Sony KV-32S20

Friends doing different tests I noticed that I heard a noise near the fly back which increases when I bring the high voltage cable to the chassis ground, so the fly back is leaking.
It has been impossible so far to get said fly back. I don't know if it can be replaced by another, or you who advise me? I wouldn't want to miss the tv yet. Thank you.
Well when I connected the tester tip to measure screen voltage, the TV turned on again. picture ok. screen voltage ok. However, turn off the TV and turn it on again to turn on without image but with audio. Heater lights the TRC filaments. If I upload the screen to the maximum I can see some clouds, but no video.
What advise me friends? thank you
If I walked while measuring, the divider (internal flyback) that gives focus and there screen tension could be wrong. In that case you have to change the flyback. You could repeat the measurement to see what happens, also try pressing the flyback potentiometers (sometimes they give false contact). Lift the focus and screen connections of the trc board (there may be leaks). But the most important thing is to be sure whether or not it has focus and screen tensions while it fails. The flyback can be replaced by another that works with the same voltage and outputs even if the pin distribution changes. Luck
Well folks I decided to solve all the clues that are in the path of abl including all the jungles IC pins and the problems were solved. The TV has been working for half an hour and everything is going well.
Please tell me one thing. When the TV is turned off, but connected to the network, it is in stand by the transistors of the source are heated anyway. Is this normal for being in stand by?
