Meade etx-105ec

Question

Hello,
the major problem wiht the scope is that the focus whell does not work in manual or automatic mode. It was not working well, kind of stiff, but now the adjusting k**b just backs out of the housing tube and when you look though the eye piece nothing can be viewed at all!
I phone Meade and they said they no longer service this unit and it is past it's service life?
