Default JVC GR-S77 camcorder fixing help

hello,

i'm in the process of collecting some late 80's early 90's camcorders.
i probabely won't surprise you by saying than most of their issues is a bunch of bad capacitors...

i've recently worked on this one, but i face an issue i don't really understand.
and i'm not really a camera expert anyway
i'll get the service manual soon (paper version), but some help is always welcome.

the issue is there's some green/red smearing appearing in high contrast situation.
here's a shooting of what happen : https://youtu.be/lLuaDVilc_4

seems realted to an AGC problem? don't know...

other than that, it work not so bad and give pretty good results when the exposure is stable
here's an exemple directly from camera output : https://youtu.be/4i_-TRU9lrk

thanks
