Local oscillator alignment is usually what causes off frequency tuning, though if this has AFC try turning it off to verify local oscillator doesn't snap back to normal.... AFC takes detector voltage and uses it to pull the local osc to peak signal... If the AFC bus is wildly wrong it might be able to feign a non-existent local osc alignment issue.
Not a bad idea to atleast check IF pass band with a generator too.
