Please read the above referenced post by Johnathan Carr. He explains that an accumulation of magnetic particles in the area of the magnets and coil can displace the cantilever alignment. He states that the Lyra cartridge can be cleaned internally (professionally) to remedy the fault.
I haven't researched how applicable this would be to your cartridge, but think it would be worthwhile for you to look into, especially if you have no recollection of contacting your cartridge in a manner to cause a bend / misalignment. Good Luck
