  Low scale seesaw models, like low scale type II, inverse (ISS), and linear
seesaw (LSS) models provide an interesting mechanism to obtain light neutrino
masses and mixings, as they can be tested in future TeV scale experiments.
Discrete flavour symmetry groups like $A_4$ can be incorporated to explain the
flavour structure of particles. But, so far, nothing is known about dynamics of
flavour symmetry - scale of its breaking, or VEV alignment of the flavon
fields. In a recent study [1], we have investigated and shed light on how to
pinpoint the favoured VEV alignment of the flavon field using light neutrino
oscillation data. In this work, for the first time, we present an analysis on
dependence of light neutrino masses on scale of flavon VEV in these three
seesaw models, and comment on how this information can be used to discriminate
among them. We also discuss about the estimated value of the constant $F$ which
can constrain various coupling constants of the model, cut-off scale of the
theory and scale of flavour symmetry breaking. This study can provide useful
insight into the hitherto unknown dynamics of flavour symmetry and hence can
contribute as an important ingredient in the model building for future studies.
