  We propose a class of left-right symmetric models (LRSMs) with spontaneous D
parity breaking, where SU(2)_R breaks at the TeV scale while discrete
left-right symmetry breaks around 10^9 GeV. By embedding this framework in a
non-supersymmetric SO(10) Grand Unified Theory (GUT) with Pati-Salam symmetry
as the highest intermediate breaking step, we obtain g_R / g_L ~ 0.6 between
the right- and left-handed gauge couplings at the TeV scale. This leads to a
suppression of beyond the Standard Model phenomena induced by the right-handed
gauge coupling. Here we focus specifically on the consequences for neutrinoless
double beta decay, low energy lepton flavour violation and LHC signatures due
to the suppressed right handed currents. Interestingly, the reduced g_R allows
us to interpret an excess of events observed recently in the range of 1.9 TeV
to 2.4 TeV by the CMS group at the LHC as the signature of a right handed gauge
boson in LRSMs with spontaneous D parity breaking. Moreover, the reduced
right-handed gauge coupling also strongly suppresses the non-standard
contribution of heavy states to the neutrinoless double beta decay rate as well
as the amplitude of low energy lepton flavour violating processes. In a
dominant type-II Seesaw mechanism of neutrino mass generation, we find that
both sets of observables provide stringent and complimentary bounds which make
it challenging to observe the scenario at the LHC.
