  We have considered a model, originally proposed by Ma and Wegman, where the
mixing pattern in neutrino sector is explained with three Higgs doublets, six
Higgs triplets and $A_4$ symmetry. The mixing pattern is explained with the
help of vacuum expectation values (VEVs) of the above mentioned doublets and
triplets. In order to study about the VEVs of the scalar fields, we construct
the full invariant scalar potential of this model. After minimizing this scalar
potential, we have found that two Higgs triplets can acquire zero VEVs. In
order to generate non-zero VEVs to all the six Higgs triplets, we have added
two more Higgs doublets to the model. Thereafter we have demonstrated that the
current neutrino oscillation data can be consistently explained in our model.
To study some phenomenological implications of this model, we have worked out
on the branching ratios for lepton flavor violating decays.
