Consider the class of rings $R$ with identity such that any left $R$-module has a non-zero injective homomorphic image. Any such ring is clearly a left V-ring. Is it true that any such ring must be semisimple (artinian) ?

    $\begingroup$ Do you mean that any module has a non-trivial quotient which is an injective module? $\endgroup$ Oct 2, 2013 at 10:30

Your class of rings is exactly the class of left V-rings: Let $R$ be a left V-ring and $M$ a non-zero left $R$-module. Let $0\neq m\in M$. Then $Rm$ has a maximal submodule and thus there is an epimorphism $\phi\colon Rm\to S$ with $S$ simple. Since $S$ is injective by assumption, the homomorphism $\phi$ extends from $Rm$ to $M$ and thus $S$ is a non-zero injective homomorphic image of $M$.

Since there are left V-rings that are not semisimple, the answer to your question is "No".
