If the TV is fine using an RF connection for an extended period, that does suggest the tube and other components are still fine and validates this theory. If it plays up with RF too, then the scart connection could be a red herring - its possible wiggling the scart is moving other components affected in that case.
If its fine on RF and only scart has the issue, its a fairly simple job to resolder the joints from scart input to motherboard. If you've no experience of soldering I'll not suggest you try it yourself, but its not a terrifying one to attempt.
I guess the question is: If you've nobody else to do it for you, are you prepared to sacrifice the telly trying? A professional repair will probably cost more than a replacement CRT these days.
