It’s a myth that every single gene on the X chromosome is silenced during X-linked inactivation.
In reality, many escape inactivation and are still expressed. It’s the lack of these that cause many (if not all) of the problems in Turner’s syndrome.
If you want to read up more on which escape X-inactivation, search “four core genotype” model and go from there
