Need help please ! :( Horizontal problem (KV-29LS35B)

Hello!

As you can see in the video, I'm having a problem with my horizontal image. :(
I had noticed this issue from time to time before, but it was really rare, about once every two months and it only lasted a few seconds.

Now, it’s happening more and more often, but it’s completely random, it can start as soon as I turn on the monitor or after 3 hours of gaming.
Sometimes, the image stretches out a lot for 0.5 seconds, then goes back to normal.

I thought it was a cold solder and discharge the tv for the first time (yay !) but it is more hard than i tough to troubleshoot this.

Here is the service manual : https://ia801907.us.archive.org/4/items/manualsbase-id-105626/105626.pdf

If someone with more knowledge than me (I'm a complete newbi in those stuff and try to learn) can help me it would be greatly appreciated !

Thanks !
