I would think that make you have something wrong with the main video IC and not the jungle IC. Because the OSD works, that could indicate that things are okay downstream from where the IF and whatnot is taking place
It could be something around that IC or possibly a cracked solder joint or something. Maybe if there's a video input board it could also be around there.
One thing you can try is to use cold spray (or a can of compressed air upside-down) and freeze the IC or things like supporting transistors around that area. What you would be looking for is some kind of clear and obvious change in the picture when you hit a specific component with the cold. Sometimes (not always) that can momentarily repair a failing component to give you a clue. I suggest this because you seem to have a problem when it warms up, so it's possible that it's temperature related
Other than that not sure. I don't have as much experience as the older members of the forum, but hope that helps a bit.
