Hi mirrored,
yes, this can be fixed without great trouble by any decent repair person. Often inactivity (a Leica that has not been used much recently) can lead to the framelines not being displayed properly.
Sometimes exercising the selection lever can help to solve the problem, though in your case it sounds like you have tried this to no avail.
I have never had to pay for such a repair, but I assume it is not among the problematic repairs, and thus should not cost too much.
Enjoy your M2!
