  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 demonstrated that, in order to consistently explain the
neutrino mixing pattern, one has to introduce two more Higgs doublets into this
model. To study some phenomenological implications of this model, we have
worked out on the branching ratios for lepton flavor violating decays.
