First thing I'd suggest is to turn it over and blow out dust.  They are
optical devices; dust accumulating on any of the pieces of the optical
path has the potential to impair functionality.

If that fails, take it apart (in my admittedly limited experience all
you need is a #2 Phillips screwdriver) and give it a more thorough

Failing that, it may, yes, need replacement.
